First, my credentials. Well. I can spell my own name, though I don't usually know exactly how old I am. I'm within a year or two, but I'm usually wrong until I've done some subtraction. I teach composition and like to write calculus equations on the board when I take classes in poetry writing. But, here's my real credentials: consider what is written herein in conjunction with what the various instructions on SOPs that you've read have said, with the requirements the program you are applying to has put forth, and with your own experience as a writer. Do you think I know what I'm talking about? Should you pay any attention to it? Is any of it useful?
 
Second, I'm not going to give you a formula for what the standard SOP is like, or a list of things the various thousands of admissions committees will be looking for. There are plenty of prescriptions on the internet, many of them written by professors who have presumably gotten sick of badly written SOPs.
 
Third, I'm not promising that SOP writing be easier after this. It'll be harder, actually. I'm not promising that you'll get in to any place you desire, or that there is any one best thing to put in the SOP to get noticed. That would be totally impossible. Each discipline has its own needs and values, as does each university, each department, and each faculty member on the admissions committee (adcomm). There is no one size and it doesn't fit most, let alone all. There are conventions (use Standard English, for one), but other than include your research interests, I won't advocate that any one thing is strictly necessary. I leave that up to the more knowledgeable.
 
The advice:
 
First thing is to deeply understand that you should write an SOP for each program. Most people take this to mean write one master SOP and then tweak as necessary to make the one SOP applicable to each university (U of A becomes U of B, Professor X becomes Professor Y). You can do that. You can be very successful doing that. You most likely, really shouldn't do it.
 
The next thing to understand is the SOP's purpose. Why do the adcomms want to see SOPs? Shouldn't transcripts, letters of recommendation, and a writing sample do it? After all, transcripts and samples show the actual scholarship and the letters verify it. The SOP isn't for showing scholarship off, or to act like a resume, or anything. So why do the adcomms want an SOP? Why are the SOPs one of those make-it-or-fail things? What is the SOP's purpose? In job hunting terms, the SOP is like a cover letter. The cover letter is to make clear connections between the resume and the job ad. For you, its primary purpose is to make the adcomm offer you admission with full funding. For the adcomm, its primary purpose is to help them see how you would fit into their program (make connections between their program and you). By fit, I mean do they have faculty (or enough faculty) in your area of research interest that can advise, mentor, supervise, and/or committee you through the program to get your degree? Do you have the kind of understanding of the discipline, your research interests, and their program that would make you successful? Do they have something to teach you? Offer you? What can you offer them? They want to brag on you as much as you want to brag about them. If they offer you admission, will you be a good scholar? A good student? Here is the most basic question the SOP should answer: What is it about you that makes you a better prospect than everyone else who's applying?
 
Understanding the SOP's purpose, in practical terms, means that you will know what to put into it and what to leave out of it. And how to phrase it.
 
So, with the purpose in mind, there comes the question: what should you put into it and leave out of it? What format should you use? (MLA? APA? Is footnoting okay?! What about citation?!) Should I stick in a personal story that everyone seems to recommend, except for the half that don't? My research interests? The story about why I got on F in that one, very important class? I'm not going to answer those questions because I can't. Every discipline and department is different. I will give you an answer you won't like: research. Find out the requirements each program you're interested in has for the SOP, think of the SOP's purpose: and now research.
 
Research is one of the basic keys to writing an SOP. It's no different than the writing sample you'll be including in your application packet. For each program you apply to, do some research. How much research you need to do depends on a lot of things, the least of which is your personality. More research does not automatically mean a better SOP. Less research doesn't automatically mean a better one, either. What makes the right amount of research? The ability to craft an SOP that is specific for the program that you're getting into. Here's some ideas (not an exhaustive, inclusive list of what to do) on what to research:
The program itself. Look at the recent graduates and, if possible, read their theses and/or dissertations, at least in part. The acknowledgements can give you an idea about the program's culture. The introduction can give you an idea about what kind of scholarship the program produces and expects. It will also, and this is very important, give you an idea as to how the program uses language. If you speak to them in their own language, that helps your case. You've likely done this, if not, seriously, you should have done this. Look at the program's website and read it all. What kind of classes are offered for both undergrad and grad. Who are the faculty, the tenured, the assistant, the visiting, the emeritus, and the graduate students. What kind of ties to the community (both academic and their local town) do they like to talk about? Do they talk about how their graduate students are working with community partners? Do they host conferences? What happened at the last one? This gives you a taste of the program's culture. The faculty. All of them that might be on the adcomm and the ones that are relevant or somewhat relevant to your interests. Crack open JSTOR etc. and search for recent faculty publications. If you're basing your interest on a faculty member on the interests they've got listed on the site and a reference to them in an article from a decade ago, or worse, only their reputation, you don't have a strong basis to establish clear reasons why they have anything to offer you. Read their recent publications, see who they name drop in terms of theory, other faculty, and so on. Make a list of what each faculty member can offer you in terms of research, not just the ones that are directly related to it. If you're into studying apples, but Dr. V works with oranges, think about how Dr. V's work might help you out. Take notes when you research. Each program has a bunch of people, and you're likely applying to multiple programs. It's easier to refer to notes than to go back and look it up all over again. What's happening in the field with your current research interests, if necessary. This is so you can situate your research interests in the discipline, and then situation your research interests in the program. You can just tell them what you're research interests are and leave the situating to them, but you can lose that chance to sell yourself as the best amongst the rest. Research you. Yup. You. Scribble out some lists or paragraphs or whatever that inventories you. Who are your influences? Who are the theorists you keep coming back to? Who are the theorists you loathe, mock, and/or ridicule? What are your research interests in general and specifically and anywhere in between? Some SOPs will need to be more general, some will need to be more specific. Length restrictions, what you found out about the program, the faculty, the state of the discipline, and so on, can alter this for you. What kind of scholar are you? Student? What's the difference? How do you manage your time? Stress? Health? Do you expect to bring your dog? Do you have health issues? Do you have any academic things that are a negative? If you do, how negative are they? It's easy to see that as an either it's entirely bad, or it's somewhere in the huge good category, but some things are negatives that need to be addressed for certain programs, while other negatives can be ignored, or you should discuss with the one relevant letter writer so they can address it. While Sam ultimately received a C in the Research Methods course, the grade doesn't reflect the actual scholarship as Sam fell ill during the mid-term and consequently failed it; my course policies do not permit re-taking the test. What are the good things about you? Not just the grades, awards, publications, and presentations, but also the character traits. What are you weaknesses? Don't do the job interview baloney, my greatest weakness is my perfectionism. Of course, the important, probably ought to be on the SOP questions: why grad school? What will you do with the degree you want? Why are into the research you're into? Why that particular school? Why are you worth admission and funding?
 
Research the assistanceships. Some SOPs will want you to write a bit about teaching or research with assistanceships in mind. So, do a bit of research on what these entail in the programs you're looking at. What do they do and how do they get it? Have you done assistanceships in the past? If so, what were they like? Do you have a teaching philosophy? If not, make one. Have you done anything that can be discussed in terms of the assistanceship? I taught kung-fu to white belt children, so I have teaching experience. I was part of the state herpetological society and went out to help them with their field counts twice a year. I learned that licking petrie dishes is always a bad idea, no matter how much they resemble pistachio ice cream.
 
Research SOPs. You're doing that, right? Go on to forums (like this one) and read the SOPs people have posted and then read the responses. Look particularly at SOPs in your discipline or related disciplines. Psychology might look at other social sciences. Physics might tell the joke about the Higgs Boson and Sunday mass. Bear in mind that the people responding to and/or criticizing the posted SOPs are likely not on an adcomm. Some have been  or will be, but it's not likely they'll be on the adcomm you're hoping will like you best. However, you can start to get a sense of what SOPs are like. What format is it in? Does yours look like everyone else's? Do you have the exact same opening sentence as half of the people hoping to get into a program in your discipline? I've always wanted to be a librarian since those wonderful, summer days I spent in my (relative of choice)'s home library. 
 
So, to take stock. First, understand the purpose. Second, research. A lot. Let the purpose of the SOP guide your research efforts.
 
Next, get the specific requirements for the SOP from each program. Make a list of similarities. If they all ask for a statement of your research interest, score! One sentence fits most! Most of them will be of different lengths and will have different ideas of what specific information they want. Most won't tell you enough, aside from length and one or two "should have" things. They mostly won't tell you if you should use APA or if you should footnote, or how to format it. Single space? Double space? They will tell you whether it should be on paper or what kind of file format to use. I have only one suggestion: consistency. Okay, two suggestions: unless otherwise specified, don't include anything other than the SOP. No bibliography or footnotes. If you quote or paraphrase someone, cite them in the text the way they do it in the average newspaper article. As Scooby says, "Ruh-roh!"
 
Now, start writing. Create something of a master SOP, or a set of master sentences for the SOPs. Some things should be in every one of them, like what your research interests are. Because length requirements are different for each program, you should work out more than one sentence or set of sentences for each thing you plan to put into more than one SOP. Have a more detailed explanation of your research interests and a more concise one. Even though this might be central and, perhaps, most important to the SOP, you don't want most of a short SOP taken up by one thing. Make these sentences do extra duties. If they can explain not only why you're into what you're into, but also why it's significant to the discipline/program, and how the program factors into it, bonus! The more functions one sentence can serve, with clear, readable logic, the more room you have in the length requirements to bring in other things. Think of this master SOP as more of a set of sentences you can hang on the individual SOP's unique structure. A flesh and skeleton metaphor can work here. You can order all SOPs at this point, you'll probably want to put research interests in the middle or toward the end, rather than in the first sentence, but the key here is that the skeleton of the individual SOP and most of its flesh will come from the needs of the program you're writing it for, not from some predetermined formula. No generically applicable, master SOP that has a few tweaks here and there.
 
Here's the thing. The SOP is one of the most important documents you'll write in your life. It's not something that should be done in a few hours, after looking at the program website and spending some time on the net searching for a how-to-write-an-SOP-guide. It takes work backed by research. The readers can tell quite easily how much research you've done on them by the way you structure and write your SOP. They can tell if you're sending out a generic SOP to several programs because it will be too general. You can't change faculty names in and out, along with a detail or two that makes it seem tailored to the program. The individual SOP should be tailored from the beginning. Some sentences won't change much, so you can pre-write them. But how they fit into each SOP, the reasoning you'll use to try to convince the adcomm that you're the best applicant, and the perspective you'll take all the way to the words you use should be done with the program in mind. It shouldn't be generic. Even if it doesn't seem noticeably generic to you, that doesn't mean that the adcomm won't notice it. They read many, many SOPs every year. People who read SOPs develop a sense about the generic, the cut and paste work.
 
How to name drop gracefully, or bring up the theory and histories and whatnot you're working with when there's only a teeny amount of space for everything? That's a bit easier than it might seem. It's not in the explanation; it's in the usage. If you can use the relevant theories and people and methodologies correctly in a sentence, you don't have to show the adcomm that you know how to use them, or how they're related, by explaining it. Trust them to have enough education to make a few connections for themselves when it comes to the discipline. Example: Novels such as Twilight exemplify how Marxist alienation can be applied to childbirth. My research interest lies in the alienation of women from the product of delivery in Modernist American fiction, such as Faulkner's Sound and the Fury. (Huh, I wonder if that would really work?) Two sentences and I've referenced theory, period, history, relevance for today, and some methodology (it's literature, not science). Use it, don't explain it.
 
If possible, have a professor you know read the SOP to your preferred school and give you some advice. They know more than most other groups of people. If not possible, your current university's writing center can help, or other people who are familiar with the field, or with writing. Your high school English teacher or your English major buddy can probably say something about your grammar, but might not be as helpful as expected. Example, in English, the convention is to speak of historical people in present tense. Shakespeare writes, "To be or not to be," because he thinks it is the question. History has kittens. Shakespeare has been dead for centuries, he can't write! Past tense! Shakespeare wrote, "To be or not to be," because thought it was the question. Someone in the field is preferable!
 
Finally, a word about my real credentials. The adcomm is going to do to your application what you've just done with this post. They are going to judge your credentials (your ethos, trustworthiness, veracity, credibility, knowledge, and so on) based on the impressions they get of you from what you've written. So, be knowledgeable about you, your field, and the program, and use that knowledge well.

First, my credentials. Well. I can spell my own name, though I don't usually know exactly how old I am. I'm within a year or two, but I'm usually wrong until I've done some subtraction. I teach composition and like to write calculus equations on the board when I take classes in poetry writing.

Each discipline has its own needs and values, as does each university, each department, and each faculty member on the admissions committee (adcomm). There is no one size and it doesn't fit most, let alone all. There are conventions (use Standard English, for one), but other than include your research interests, I won't advocate that any one thing is strictly necessary. I leave that up to the more knowledgeable.
 
The advice:
 
First thing is to deeply understand that you should write an SOP for each program. Most people take this to mean write one master SOP and then tweak as necessary to make the one SOP applicable to each university (U of A becomes U of B, Professor X becomes Professor Y). You can do that. You can be very successful doing that. You most likely, really shouldn't do it.
 
The next thing to understand is the SOP's purpose. Why do the adcomms want to see SOPs? Shouldn't transcripts, letters of recommendation, and a writing sample do it? After all, transcripts and samples show the actual scholarship and the letters verify it. The SOP isn't for showing scholarship off, or to act like a resume, or anything. So why do the adcomms want an SOP? Why are the SOPs one of those make-it-or-fail things? What is the SOP's purpose? In job hunting terms, the SOP is like a cover letter. The cover letter is to make clear connections between the resume and the job ad. For you, its primary purpose is to make the adcomm offer you admission with full funding. For the adcomm, its primary purpose is to help them see how you would fit into their program (make connections between their program and you). By fit, I mean do they have faculty (or enough faculty) in your area of research interest that can advise, mentor, supervise, and/or committee you through the program to get your degree? Do you have the kind of understanding of the discipline, your research interests, and their program that would make you successful? Do they have something to teach you? Offer you? What can you offer them? They want to brag on you as much as you want to brag about them. If they offer you admission, will you be a good scholar? A good student? Here is the most basic question the SOP should answer: What is it about you that makes you a better prospect than everyone else who's applying?
 
Understanding the SOP's purpose, in practical terms, means that you will know what to put into it and what to leave out of it. And how to phrase it.
 
So, with the purpose in mind, there comes the question: what should you put into it and leave out of it? What format should you use? (MLA? APA? Is footnoting okay?! What about citation?!) Should I stick in a personal story that everyone seems to recommend, except for the half that don't? My research interests? The story about why I got on F in that one, very important class? I'm not going to answer those questions because I can't. Every discipline and department is different. I will give you an answer you won't like: research. Find out the requirements each program you're interested in has for the SOP, think of the SOP's purpose: and now research.
 
Research is one of the basic keys to writing an SOP. It's no different than the writing sample you'll be including in your application packet. For each program you apply to, do some research. How much research you need to do depends on a lot of things, the least of which is your personality. More research does not automatically mean a better SOP. Less research doesn't automatically mean a better one, either. What makes the right amount of research? The ability to craft an SOP that is specific for the program that you're getting into. Here's some ideas (not an exhaustive, inclusive list of what to do) on what to research:
The program itself. Look at the recent graduates and, if possible, read their theses and/or dissertations, at least in part. The acknowledgements can give you an idea about the program's culture. The introduction can give you an idea about what kind of scholarship the program produces and expects. It will also, and this is very important, give you an idea as to how the program uses language. If you speak to them in their own language, that helps your case. You've likely done this, if not, seriously, you should have done this. Look at the program's website and read it all. What kind of classes are offered for both undergrad and grad. Who are the faculty, the tenured, the assistant, the visiting, the emeritus, and the graduate students. What kind of ties to the community (both academic and their local town) do they like to talk about? Do they talk about how their graduate students are working with community partners? Do they host conferences? What happened at the last one? This gives you a taste of the program's culture. The faculty. All of them that might be on the adcomm and the ones that are relevant or somewhat relevant to your interests. Crack open JSTOR etc. and search for recent faculty publications. If you're basing your interest on a faculty member on the interests they've got listed on the site and a reference to them in an article from a decade ago, or worse, only their reputation, you don't have a strong basis to establish clear reasons why they have anything to offer you. Read their recent publications, see who they name drop in terms of theory, other faculty, and so on. Make a list of what each faculty member can offer you in terms of research, not just the ones that are directly related to it. If you're into studying apples, but Dr. V works with oranges, think about how Dr. V's work might help you out. Take notes when you research. Each program has a bunch of people, and you're likely applying to multiple programs. It's easier to refer to notes than to go back and look it up all over again. What's happening in the field with your current research interests, if necessary. This is so you can situate your research interests in the discipline, and then situation your research interests in the program. You can just tell them what you're research interests are and leave the situating to them, but you can lose that chance to sell yourself as the best amongst the rest. Research you. Yup. You. Scribble out some lists or paragraphs or whatever that inventories you. Who are your influences? Who are the theorists you keep coming back to? Who are the theorists you loathe, mock, and/or ridicule? What are your research interests in general and specifically and anywhere in between? Some SOPs will need to be more general, some will need to be more specific. Length restrictions, what you found out about the program, the faculty, the state of the discipline, and so on, can alter this for you. What kind of scholar are you? Student? What's the difference? How do you manage your time? Stress? Health? Do you expect to bring your dog? Do you have health issues? Do you have any academic things that are a negative? If you do, how negative are they? It's easy to see that as an either it's entirely bad, or it's somewhere in the huge good category, but some things are negatives that need to be addressed for certain programs, while other negatives can be ignored, or you should discuss with the one relevant letter writer so they can address it. While Sam ultimately received a C in the Research Methods course, the grade doesn't reflect the actual scholarship as Sam fell ill during the mid-term and consequently failed it; my course policies do not permit re-taking the test. What are the good things about you? Not just the grades, awards, publications, and presentations, but also the character traits. What are you weaknesses? Don't do the job interview baloney, my greatest weakness is my perfectionism. Of course, the important, probably ought to be on the SOP questions: why grad school? What will you do with the degree you want? Why are into the research you're into? Why that particular school? Why are you worth admission and funding?
 
Research the assistanceships. Some SOPs will want you to write a bit about teaching or research with assistanceships in mind. So, do a bit of research on what these entail in the programs you're looking at. What do they do and how do they get it? Have you done assistanceships in the past? If so, what were they like? Do you have a teaching philosophy? If not, make one. Have you done anything that can be discussed in terms of the assistanceship? I taught kung-fu to white belt children, so I have teaching experience. I was part of the state herpetological society and went out to help them with their field counts twice a year. I learned that licking petrie dishes is always a bad idea, no matter how much they resemble pistachio ice cream.
 
Research SOPs. You're doing that, right? Go on to forums (like this one) and read the SOPs people have posted and then read the responses. Look particularly at SOPs in your discipline or related disciplines. Psychology might look at other social sciences. Physics might tell the joke about the Higgs Boson and Sunday mass. Bear in mind that the people responding to and/or criticizing the posted SOPs are likely not on an adcomm. Some have been  or will be, but it's not likely they'll be on the adcomm you're hoping will like you best. However, you can start to get a sense of what SOPs are like. What format is it in? Does yours look like everyone else's? Do you have the exact same opening sentence as half of the people hoping to get into a program in your discipline? I've always wanted to be a librarian since those wonderful, summer days I spent in my (relative of choice)'s home library. 
 
So, to take stock. First, understand the purpose. Second, research. A lot. Let the purpose of the SOP guide your research efforts.
 
Next, get the specific requirements for the SOP from each program. Make a list of similarities. If they all ask for a statement of your research interest, score! One sentence fits most! Most of them will be of different lengths and will have different ideas of what specific information they want. Most won't tell you enough, aside from length and one or two "should have" things. They mostly won't tell you if you should use APA or if you should footnote, or how to format it. Single space? Double space? They will tell you whether it should be on paper or what kind of file format to use. I have only one suggestion: consistency. Okay, two suggestions: unless otherwise specified, don't include anything other than the SOP. No bibliography or footnotes. If you quote or paraphrase someone, cite them in the text the way they do it in the average newspaper article. As Scooby says, "Ruh-roh!"
 
Now, start writing. Create something of a master SOP, or a set of master sentences for the SOPs. Some things should be in every one of them, like what your research interests are. Because length requirements are different for each program, you should work out more than one sentence or set of sentences for each thing you plan to put into more than one SOP. Have a more detailed explanation of your research interests and a more concise one. Even though this might be central and, perhaps, most important to the SOP, you don't want most of a short SOP taken up by one thing. Make these sentences do extra duties. If they can explain not only why you're into what you're into, but also why it's significant to the discipline/program, and how the program factors into it, bonus! The more functions one sentence can serve, with clear, readable logic, the more room you have in the length requirements to bring in other things. Think of this master SOP as more of a set of sentences you can hang on the individual SOP's unique structure. A flesh and skeleton metaphor can work here. You can order all SOPs at this point, you'll probably want to put research interests in the middle or toward the end, rather than in the first sentence, but the key here is that the skeleton of the individual SOP and most of its flesh will come from the needs of the program you're writing it for, not from some predetermined formula. No generically applicable, master SOP that has a few tweaks here and there.
 
Here's the thing. The SOP is one of the most important documents you'll write in your life. It's not something that should be done in a few hours, after looking at the program website and spending some time on the net searching for a how-to-write-an-SOP-guide. It takes work backed by research. The readers can tell quite easily how much research you've done on them by the way you structure and write your SOP. They can tell if you're sending out a generic SOP to several programs because it will be too general. You can't change faculty names in and out, along with a detail or two that makes it seem tailored to the program. The individual SOP should be tailored from the beginning. Some sentences won't change much, so you can pre-write them. But how they fit into each SOP, the reasoning you'll use to try to convince the adcomm that you're the best applicant, and the perspective you'll take all the way to the words you use should be done with the program in mind. It shouldn't be generic. Even if it doesn't seem noticeably generic to you, that doesn't mean that the adcomm won't notice it. They read many, many SOPs every year. People who read SOPs develop a sense about the generic, the cut and paste work.
 
How to name drop gracefully, or bring up the theory and histories and whatnot you're working with when there's only a teeny amount of space for everything? That's a bit easier than it might seem. It's not in the explanation; it's in the usage. If you can use the relevant theories and people and methodologies correctly in a sentence, you don't have to show the adcomm that you know how to use them, or how they're related, by explaining it. Trust them to have enough education to make a few connections for themselves when it comes to the discipline. Example: Novels such as Twilight exemplify how Marxist alienation can be applied to childbirth. My research interest lies in the alienation of women from the product of delivery in Modernist American fiction, such as Faulkner's Sound and the Fury. (Huh, I wonder if that would really work?) Two sentences and I've referenced theory, period, history, relevance for today, and some methodology (it's literature, not science). Use it, don't explain it.
 
If possible, have a professor you know read the SOP to your preferred school and give you some advice. They know more than most other groups of people. If not possible, your current university's writing center can help, or other people who are familiar with the field, or with writing. Your high school English teacher or your English major buddy can probably say something about your grammar, but might not be as helpful as expected. Example, in English, the convention is to speak of historical people in present tense. Shakespeare writes, "To be or not to be," because he thinks it is the question. History has kittens. Shakespeare has been dead for centuries, he can't write! Past tense! Shakespeare wrote, "To be or not to be," because thought it was the question. Someone in the field is preferable!
 
Finally, a word about my real credentials. The adcomm is going to do to your application what you've just done with this post. They are going to judge your credentials (your ethos, trustworthiness, veracity, credibility, knowledge, and so on) based on the impressions they get of you from what you've written. So, be knowledgeable about you, your field, and the program, and use that knowledge well.

I wasn't going to reply because your point is important and me sniping is counterproductive to the purpose of the thread. But I've been thinking about this for a few months and I'm at the tail end of a paper, which I am procrastinating hard on. My judgment isn't what it ought to be. Still, I think I do have something productive to add, rather than just being snotty for the sake of being snotty. I also feel that what I'm going to say is likely going to come across snotty, anyway. It is not at all my intention to start an argument, or continue an old argument, or whatever. It is my intention to draw attention (if anyone has any interest in this) to the rhetorical implications of the way the discussion played out.


It's not what you said; it's how you said it. It's not what I said; it's the way I said it.


Tone matters. I wasn't as invested in paying attention to your point as I was in reacting to your tone. I don't know why you chose to phrase yourself the way you did in your initial post, nor what you intended to have people do with your post. I do know what happened. Reaction, not deliberation. And this is why I think it's important enough to address, instead of letting sleeping dogs lie. With most of the writing we do, we have no idea who is on the other end and how they will take it. I'm not concerned with the rights, the wrongs, or the indifferents of the discussion itself. It is what it is. (That fact that all of the snotty barbs essentially expressed agreement on the basic claim is cake.) I am about the whole what can I learn from this cliche. And since this is a thread ostensibly about how to write something important, of a persuasive nature, I think the whole what can I learn from this cliche might be of use.

The general point of this, and why I thought it important enough to risk stirring the pot all over again, is: a key part of the rhetorical art is phrasing oneself for a desired result on the part of the reader. Rhetoric is inherently manipulative (which is why politicians use it as a dirty word). Sometimes people make rhetorical choices deliberately and sometimes they don't. And, intentional or not, rhetorical choices exercise limited, um, control (for lack of a better word) over a reader's response. It's the reader's choice to think, react, be offended, laugh, or whatever. However, it's the writer's choice to consider probable reader responses when making writing choices.

Writing is a social relationship, which means it's all about choices made by the writer and, if there are any, the reader.

Hm. That'll cover it.

First, my credentials. Well. I can spell my own name, though I don't usually know exactly how old I am. I'm within a year or two, but I'm usually wrong until I've done some subtraction. I teach composition and like to write calculus equations on the board when I take classes in poetry writing. But, here's my real credentials: consider what is written herein in conjunction with what the various instructions on SOPs that you've read have said, with the requirements the program you are applying to has put forth, and with your own experience as a writer. Do you think I know what I'm talking about? Should you pay any attention to it? Is any of it useful?
 
Second, I'm not going to give you a formula for what the standard SOP is like, or a list of things the various thousands of admissions committees will be looking for. There are plenty of prescriptions on the internet, many of them written by professors who have presumably gotten sick of badly written SOPs.
 
Third, I'm not promising that SOP writing be easier after this. It'll be harder, actually. I'm not promising that you'll get in to any place you desire, or that there is any one best thing to put in the SOP to get noticed. That would be totally impossible. Each discipline has its own needs and values, as does each university, each department, and each faculty member on the admissions committee (adcomm). There is no one size and it doesn't fit most, let alone all. There are conventions (use Standard English, for one), but other than include your research interests, I won't advocate that any one thing is strictly necessary. I leave that up to the more knowledgeable.

Finally, a word about my real credentials. The adcomm is going to do to your application what you've just done with this post. They are going to judge your credentials (your ethos, trustworthiness, veracity, credibility, knowledge, and so on) based on the impressions they get of you from what you've written. So, be knowledgeable about you, your field, and the program, and use that knowledge well.

First, my credentials. Well. I can spell my own name, though I don't usually know exactly how old I am. I'm within a year or two, but I'm usually wrong until I've done some subtraction. I teach composition and like to write calculus equations on the board when I take classes in poetry writing. But, here's my real credentials: consider what is written herein in conjunction with what the various instructions on SOPs that you've read have said, with the requirements the program you are applying to has put forth, and with your own experience as a writer. Do you think I know what I'm talking about? Should you pay any attention to it? Is any of it useful?
 
Second, I'm not going to give you a formula for what the standard SOP is like, or a list of things the various thousands of admissions committees will be looking for. There are plenty of prescriptions on the internet, many of them written by professors who have presumably gotten sick of badly written SOPs.
 
Third, I'm not promising that SOP writing be easier after this. It'll be harder, actually. I'm not promising that you'll get in to any place you desire, or that there is any one best thing to put in the SOP to get noticed. That would be totally impossible. Each discipline has its own needs and values, as does each university, each department, and each faculty member on the admissions committee (adcomm). There is no one size and it doesn't fit most, let alone all. There are conventions (use Standard English, for one), but other than include your research interests, I won't advocate that any one thing is strictly necessary. I leave that up to the more knowledgeable.
 
The advice:
 
First thing is to deeply understand that you should write an SOP for each program. Most people take this to mean write one master SOP and then tweak as necessary to make the one SOP applicable to each university (U of A becomes U of B, Professor X becomes Professor Y). You can do that. You can be very successful doing that. You most likely, really shouldn't do it.
 
The next thing to understand is the SOP's purpose. Why do the adcomms want to see SOPs? Shouldn't transcripts, letters of recommendation, and a writing sample do it? After all, transcripts and samples show the actual scholarship and the letters verify it. The SOP isn't for showing scholarship off, or to act like a resume, or anything. So why do the adcomms want an SOP? Why are the SOPs one of those make-it-or-fail things? What is the SOP's purpose? In job hunting terms, the SOP is like a cover letter. The cover letter is to make clear connections between the resume and the job ad. For you, its primary purpose is to make the adcomm offer you admission with full funding. For the adcomm, its primary purpose is to help them see how you would fit into their program (make connections between their program and you). By fit, I mean do they have faculty (or enough faculty) in your area of research interest that can advise, mentor, supervise, and/or committee you through the program to get your degree? Do you have the kind of understanding of the discipline, your research interests, and their program that would make you successful? Do they have something to teach you? Offer you? What can you offer them? They want to brag on you as much as you want to brag about them. If they offer you admission, will you be a good scholar? A good student? Here is the most basic question the SOP should answer: What is it about you that makes you a better prospect than everyone else who's applying?
 
Understanding the SOP's purpose, in practical terms, means that you will know what to put into it and what to leave out of it. And how to phrase it.
 
So, with the purpose in mind, there comes the question: what should you put into it and leave out of it? What format should you use? (MLA? APA? Is footnoting okay?! What about citation?!) Should I stick in a personal story that everyone seems to recommend, except for the half that don't? My research interests? The story about why I got on F in that one, very important class? I'm not going to answer those questions because I can't. Every discipline and department is different. I will give you an answer you won't like: research. Find out the requirements each program you're interested in has for the SOP, think of the SOP's purpose: and now research.
 
Research is one of the basic keys to writing an SOP. It's no different than the writing sample you'll be including in your application packet. For each program you apply to, do some research. How much research you need to do depends on a lot of things, the least of which is your personality. More research does not automatically mean a better SOP. Less research doesn't automatically mean a better one, either. What makes the right amount of research? The ability to craft an SOP that is specific for the program that you're getting into. Here's some ideas (not an exhaustive, inclusive list of what to do) on what to research:
The program itself. Look at the recent graduates and, if possible, read their theses and/or dissertations, at least in part. The acknowledgements can give you an idea about the program's culture. The introduction can give you an idea about what kind of scholarship the program produces and expects. It will also, and this is very important, give you an idea as to how the program uses language. If you speak to them in their own language, that helps your case. You've likely done this, if not, seriously, you should have done this. Look at the program's website and read it all. What kind of classes are offered for both undergrad and grad. Who are the faculty, the tenured, the assistant, the visiting, the emeritus, and the graduate students. What kind of ties to the community (both academic and their local town) do they like to talk about? Do they talk about how their graduate students are working with community partners? Do they host conferences? What happened at the last one? This gives you a taste of the program's culture. The faculty. All of them that might be on the adcomm and the ones that are relevant or somewhat relevant to your interests. Crack open JSTOR etc. and search for recent faculty publications. If you're basing your interest on a faculty member on the interests they've got listed on the site and a reference to them in an article from a decade ago, or worse, only their reputation, you don't have a strong basis to establish clear reasons why they have anything to offer you. Read their recent publications, see who they name drop in terms of theory, other faculty, and so on. Make a list of what each faculty member can offer you in terms of research, not just the ones that are directly related to it. If you're into studying apples, but Dr. V works with oranges, think about how Dr. V's work might help you out. Take notes when you research. Each program has a bunch of people, and you're likely applying to multiple programs. It's easier to refer to notes than to go back and look it up all over again. What's happening in the field with your current research interests, if necessary. This is so you can situate your research interests in the discipline, and then situation your research interests in the program. You can just tell them what you're research interests are and leave the situating to them, but you can lose that chance to sell yourself as the best amongst the rest. Research you. Yup. You. Scribble out some lists or paragraphs or whatever that inventories you. Who are your influences? Who are the theorists you keep coming back to? Who are the theorists you loathe, mock, and/or ridicule? What are your research interests in general and specifically and anywhere in between? Some SOPs will need to be more general, some will need to be more specific. Length restrictions, what you found out about the program, the faculty, the state of the discipline, and so on, can alter this for you. What kind of scholar are you? Student? What's the difference? How do you manage your time? Stress? Health? Do you expect to bring your dog? Do you have health issues? Do you have any academic things that are a negative? If you do, how negative are they? It's easy to see that as an either it's entirely bad, or it's somewhere in the huge good category, but some things are negatives that need to be addressed for certain programs, while other negatives can be ignored, or you should discuss with the one relevant letter writer so they can address it. While Sam ultimately received a C in the Research Methods course, the grade doesn't reflect the actual scholarship as Sam fell ill during the mid-term and consequently failed it; my course policies do not permit re-taking the test. What are the good things about you? Not just the grades, awards, publications, and presentations, but also the character traits. What are you weaknesses? Don't do the job interview baloney, my greatest weakness is my perfectionism. Of course, the important, probably ought to be on the SOP questions: why grad school? What will you do with the degree you want? Why are into the research you're into? Why that particular school? Why are you worth admission and funding?
 
Research the assistanceships. Some SOPs will want you to write a bit about teaching or research with assistanceships in mind. So, do a bit of research on what these entail in the programs you're looking at. What do they do and how do they get it? Have you done assistanceships in the past? If so, what were they like? Do you have a teaching philosophy? If not, make one. Have you done anything that can be discussed in terms of the assistanceship? I taught kung-fu to white belt children, so I have teaching experience. I was part of the state herpetological society and went out to help them with their field counts twice a year. I learned that licking petrie dishes is always a bad idea, no matter how much they resemble pistachio ice cream.
 
Research SOPs. You're doing that, right? Go on to forums (like this one) and read the SOPs people have posted and then read the responses. Look particularly at SOPs in your discipline or related disciplines. Psychology might look at other social sciences. Physics might tell the joke about the Higgs Boson and Sunday mass. Bear in mind that the people responding to and/or criticizing the posted SOPs are likely not on an adcomm. Some have been  or will be, but it's not likely they'll be on the adcomm you're hoping will like you best. However, you can start to get a sense of what SOPs are like. What format is it in? Does yours look like everyone else's? Do you have the exact same opening sentence as half of the people hoping to get into a program in your discipline? I've always wanted to be a librarian since those wonderful, summer days I spent in my (relative of choice)'s home library. 
 
So, to take stock. First, understand the purpose. Second, research. A lot. Let the purpose of the SOP guide your research efforts.
 
Next, get the specific requirements for the SOP from each program. Make a list of similarities. If they all ask for a statement of your research interest, score! One sentence fits most! Most of them will be of different lengths and will have different ideas of what specific information they want. Most won't tell you enough, aside from length and one or two "should have" things. They mostly won't tell you if you should use APA or if you should footnote, or how to format it. Single space? Double space? They will tell you whether it should be on paper or what kind of file format to use. I have only one suggestion: consistency. Okay, two suggestions: unless otherwise specified, don't include anything other than the SOP. No bibliography or footnotes. If you quote or paraphrase someone, cite them in the text the way they do it in the average newspaper article. As Scooby says, "Ruh-roh!"
 
Now, start writing. Create something of a master SOP, or a set of master sentences for the SOPs. Some things should be in every one of them, like what your research interests are. Because length requirements are different for each program, you should work out more than one sentence or set of sentences for each thing you plan to put into more than one SOP. Have a more detailed explanation of your research interests and a more concise one. Even though this might be central and, perhaps, most important to the SOP, you don't want most of a short SOP taken up by one thing. Make these sentences do extra duties. If they can explain not only why you're into what you're into, but also why it's significant to the discipline/program, and how the program factors into it, bonus! The more functions one sentence can serve, with clear, readable logic, the more room you have in the length requirements to bring in other things. Think of this master SOP as more of a set of sentences you can hang on the individual SOP's unique structure. A flesh and skeleton metaphor can work here. You can order all SOPs at this point, you'll probably want to put research interests in the middle or toward the end, rather than in the first sentence, but the key here is that the skeleton of the individual SOP and most of its flesh will come from the needs of the program you're writing it for, not from some predetermined formula. No generically applicable, master SOP that has a few tweaks here and there.
 
Here's the thing. The SOP is one of the most important documents you'll write in your life. It's not something that should be done in a few hours, after looking at the program website and spending some time on the net searching for a how-to-write-an-SOP-guide. It takes work backed by research. The readers can tell quite easily how much research you've done on them by the way you structure and write your SOP. They can tell if you're sending out a generic SOP to several programs because it will be too general. You can't change faculty names in and out, along with a detail or two that makes it seem tailored to the program. The individual SOP should be tailored from the beginning. Some sentences won't change much, so you can pre-write them. But how they fit into each SOP, the reasoning you'll use to try to convince the adcomm that you're the best applicant, and the perspective you'll take all the way to the words you use should be done with the program in mind. It shouldn't be generic. Even if it doesn't seem noticeably generic to you, that doesn't mean that the adcomm won't notice it. They read many, many SOPs every year. People who read SOPs develop a sense about the generic, the cut and paste work.
 
How to name drop gracefully, or bring up the theory and histories and whatnot you're working with when there's only a teeny amount of space for everything? That's a bit easier than it might seem. It's not in the explanation; it's in the usage. If you can use the relevant theories and people and methodologies correctly in a sentence, you don't have to show the adcomm that you know how to use them, or how they're related, by explaining it. Trust them to have enough education to make a few connections for themselves when it comes to the discipline. Example: Novels such as Twilight exemplify how Marxist alienation can be applied to childbirth. My research interest lies in the alienation of women from the product of delivery in Modernist American fiction, such as Faulkner's Sound and the Fury. (Huh, I wonder if that would really work?) Two sentences and I've referenced theory, period, history, relevance for today, and some methodology (it's literature, not science). Use it, don't explain it.
 
If possible, have a professor you know read the SOP to your preferred school and give you some advice. They know more than most other groups of people. If not possible, your current university's writing center can help, or other people who are familiar with the field, or with writing. Your high school English teacher or your English major buddy can probably say something about your grammar, but might not be as helpful as expected. Example, in English, the convention is to speak of historical people in present tense. Shakespeare writes, "To be or not to be," because he thinks it is the question. History has kittens. Shakespeare has been dead for centuries, he can't write! Past tense! Shakespeare wrote, "To be or not to be," because thought it was the question. Someone in the field is preferable!

I love my spine. It's the only spine I will have and it cannot ever be replaced.
 
I have backpacks. If I'm carrying a light load (tablet, keyboard, no more than 2 trade paperback sized books, one legal pad, and assorted daily life accoutrement, then I'll use my backpack purse (no support in it). For daily use, I use a backpack that has a rigid "frame" built into the back and has straps that help me support the load with my hips, though it doesn't have a waist strap like a hiking backpack. It's not an actual frame, internal or external, but there is some rigidity there. On days when I have to tote a lot, I dork-out and use a pull-behind bag/carrier.
 
I'm old (for the average person here) and many women my age are starting to have to cover up things like hammer toes and varicose veins. If you wonder why older women wear pants and closed toed sandals to the beach, look at their daily wear. I may not be rocking the fashion scene, but unlike too many of my peer group, my feet still look fabulous naked.
 
If it's about looking professional, buy an understated bag.

I love my spine. It's the only spine I will have and it cannot ever be replaced.

Not touching the teaching-isn't-valuable-for-hiring argument.
 
That said, if you get the sense that teaching is going to be part of your hiring evaluation, keep a teaching journal that allows you to analyze what you've done over the semester, what worked, what didn't, what changes you'll implement, what things you've done that are new/original (or seem to be), and why you chose to do the things you do. At the end of the first semester, write a teaching philosophy statement and, at the end of each semester, tweak it with what you've learned.
 
If your field offers pedagogy theory and methodology studies, keep an eye on it to some extent. Eyeball the abstracts on new journal articles about pedagogy in your field, if nothing else. The more teaching oriented the field, the more these pedagogy theories should support your teaching philosophy in your teaching philosophy statement.
 
I wouldn't go totally crazy and put as much effort into this as you would your research, but do spend a few hours per semester reflecting on your teaching with an eye toward writing that teaching philosophy statement that some job openings might ask for.
 
Keep a copy of all your syllubi and assignments that you develop in some way, for future reference. Make notes on why you developed the syllabus and assignments the way you did, why you developed the grading the way you did. If you assisted a professor rather than taught your own course, make those notes about why you believe the prof developed the syllabus/assignments in a particular way and why these ways were good/bad ideas, and what you might do differently.
 
Like I said, a few hours per semester, not per week. Be casual about it, other than a teaching philosophy statement and your CV. How much this will help you depends entirely on you, your field, and your goals.
 
Keep an eye out for pedagogy publication and presentation opportunities, as well. In some fields, you shouldn't bother because they're stuck on Shaw's idea that those who can do, those who can't teach. Other fields, this can be a great place to get yourself out there.

First, my credentials. Well. I can spell my own name, though I don't usually know exactly how old I am. I'm within a year or two, but I'm usually wrong until I've done some subtraction. I teach composition and like to write calculus equations on the board when I take classes in poetry writing. But, here's my real credentials: consider what is written herein in conjunction with what the various instructions on SOPs that you've read have said, with the requirements the program you are applying to has put forth, and with your own experience as a writer. Do you think I know what I'm talking about? Should you pay any attention to it? Is any of it useful?
 
Second, I'm not going to give you a formula for what the standard SOP is like, or a list of things the various thousands of admissions committees will be looking for. There are plenty of prescriptions on the internet, many of them written by professors who have presumably gotten sick of badly written SOPs.
 
Third, I'm not promising that SOP writing be easier after this. It'll be harder, actually. I'm not promising that you'll get in to any place you desire, or that there is any one best thing to put in the SOP to get noticed. That would be totally impossible. Each discipline has its own needs and values, as does each university, each department, and each faculty member on the admissions committee (adcomm). There is no one size and it doesn't fit most, let alone all. There are conventions (use Standard English, for one), but other than include your research interests, I won't advocate that any one thing is strictly necessary. I leave that up to the more knowledgeable.
 
The advice:
 
First thing is to deeply understand that you should write an SOP for each program. Most people take this to mean write one master SOP and then tweak as necessary to make the one SOP applicable to each university (U of A becomes U of B, Professor X becomes Professor Y). You can do that. You can be very successful doing that. You most likely, really shouldn't do it.
 
The next thing to understand is the SOP's purpose. Why do the adcomms want to see SOPs? Shouldn't transcripts, letters of recommendation, and a writing sample do it? After all, transcripts and samples show the actual scholarship and the letters verify it. The SOP isn't for showing scholarship off, or to act like a resume, or anything. So why do the adcomms want an SOP? Why are the SOPs one of those make-it-or-fail things? What is the SOP's purpose? In job hunting terms, the SOP is like a cover letter. The cover letter is to make clear connections between the resume and the job ad. For you, its primary purpose is to make the adcomm offer you admission with full funding. For the adcomm, its primary purpose is to help them see how you would fit into their program (make connections between their program and you). By fit, I mean do they have faculty (or enough faculty) in your area of research interest that can advise, mentor, supervise, and/or committee you through the program to get your degree? Do you have the kind of understanding of the discipline, your research interests, and their program that would make you successful? Do they have something to teach you? Offer you? What can you offer them? They want to brag on you as much as you want to brag about them. If they offer you admission, will you be a good scholar? A good student? Here is the most basic question the SOP should answer: What is it about you that makes you a better prospect than everyone else who's applying?
 
Understanding the SOP's purpose, in practical terms, means that you will know what to put into it and what to leave out of it. And how to phrase it.
 
So, with the purpose in mind, there comes the question: what should you put into it and leave out of it? What format should you use? (MLA? APA? Is footnoting okay?! What about citation?!) Should I stick in a personal story that everyone seems to recommend, except for the half that don't? My research interests? The story about why I got on F in that one, very important class? I'm not going to answer those questions because I can't. Every discipline and department is different. I will give you an answer you won't like: research. Find out the requirements each program you're interested in has for the SOP, think of the SOP's purpose: and now research.
 
Research is one of the basic keys to writing an SOP. It's no different than the writing sample you'll be including in your application packet. For each program you apply to, do some research. How much research you need to do depends on a lot of things, the least of which is your personality. More research does not automatically mean a better SOP. Less research doesn't automatically mean a better one, either. What makes the right amount of research? The ability to craft an SOP that is specific for the program that you're getting into. Here's some ideas (not an exhaustive, inclusive list of what to do) on what to research:
The program itself. Look at the recent graduates and, if possible, read their theses and/or dissertations, at least in part. The acknowledgements can give you an idea about the program's culture. The introduction can give you an idea about what kind of scholarship the program produces and expects. It will also, and this is very important, give you an idea as to how the program uses language. If you speak to them in their own language, that helps your case. You've likely done this, if not, seriously, you should have done this. Look at the program's website and read it all. What kind of classes are offered for both undergrad and grad. Who are the faculty, the tenured, the assistant, the visiting, the emeritus, and the graduate students. What kind of ties to the community (both academic and their local town) do they like to talk about? Do they talk about how their graduate students are working with community partners? Do they host conferences? What happened at the last one? This gives you a taste of the program's culture. The faculty. All of them that might be on the adcomm and the ones that are relevant or somewhat relevant to your interests. Crack open JSTOR etc. and search for recent faculty publications. If you're basing your interest on a faculty member on the interests they've got listed on the site and a reference to them in an article from a decade ago, or worse, only their reputation, you don't have a strong basis to establish clear reasons why they have anything to offer you. Read their recent publications, see who they name drop in terms of theory, other faculty, and so on. Make a list of what each faculty member can offer you in terms of research, not just the ones that are directly related to it. If you're into studying apples, but Dr. V works with oranges, think about how Dr. V's work might help you out. Take notes when you research. Each program has a bunch of people, and you're likely applying to multiple programs. It's easier to refer to notes than to go back and look it up all over again. What's happening in the field with your current research interests, if necessary. This is so you can situate your research interests in the discipline, and then situation your research interests in the program. You can just tell them what you're research interests are and leave the situating to them, but you can lose that chance to sell yourself as the best amongst the rest. Research you. Yup. You. Scribble out some lists or paragraphs or whatever that inventories you. Who are your influences? Who are the theorists you keep coming back to? Who are the theorists you loathe, mock, and/or ridicule? What are your research interests in general and specifically and anywhere in between? Some SOPs will need to be more general, some will need to be more specific. Length restrictions, what you found out about the program, the faculty, the state of the discipline, and so on, can alter this for you. What kind of scholar are you? Student? What's the difference? How do you manage your time? Stress? Health? Do you expect to bring your dog? Do you have health issues? Do you have any academic things that are a negative? If you do, how negative are they? It's easy to see that as an either it's entirely bad, or it's somewhere in the huge good category, but some things are negatives that need to be addressed for certain programs, while other negatives can be ignored, or you should discuss with the one relevant letter writer so they can address it. While Sam ultimately received a C in the Research Methods course, the grade doesn't reflect the actual scholarship as Sam fell ill during the mid-term and consequently failed it; my course policies do not permit re-taking the test. What are the good things about you? Not just the grades, awards, publications, and presentations, but also the character traits. What are you weaknesses? Don't do the job interview baloney, my greatest weakness is my perfectionism. Of course, the important, probably ought to be on the SOP questions: why grad school? What will you do with the degree you want? Why are into the research you're into? Why that particular school? Why are you worth admission and funding?
 
Research the assistanceships. Some SOPs will want you to write a bit about teaching or research with assistanceships in mind. So, do a bit of research on what these entail in the programs you're looking at. What do they do and how do they get it? Have you done assistanceships in the past? If so, what were they like? Do you have a teaching philosophy? If not, make one. Have you done anything that can be discussed in terms of the assistanceship? I taught kung-fu to white belt children, so I have teaching experience. I was part of the state herpetological society and went out to help them with their field counts twice a year. I learned that licking petrie dishes is always a bad idea, no matter how much they resemble pistachio ice cream.
 
Research SOPs. You're doing that, right? Go on to forums (like this one) and read the SOPs people have posted and then read the responses. Look particularly at SOPs in your discipline or related disciplines. Psychology might look at other social sciences. Physics might tell the joke about the Higgs Boson and Sunday mass. Bear in mind that the people responding to and/or criticizing the posted SOPs are likely not on an adcomm. Some have been  or will be, but it's not likely they'll be on the adcomm you're hoping will like you best. However, you can start to get a sense of what SOPs are like. What format is it in? Does yours look like everyone else's? Do you have the exact same opening sentence as half of the people hoping to get into a program in your discipline? I've always wanted to be a librarian since those wonderful, summer days I spent in my (relative of choice)'s home library. 
 
So, to take stock. First, understand the purpose. Second, research. A lot. Let the purpose of the SOP guide your research efforts.
 
Next, get the specific requirements for the SOP from each program. Make a list of similarities. If they all ask for a statement of your research interest, score! One sentence fits most! Most of them will be of different lengths and will have different ideas of what specific information they want. Most won't tell you enough, aside from length and one or two "should have" things. They mostly won't tell you if you should use APA or if you should footnote, or how to format it. Single space? Double space? They will tell you whether it should be on paper or what kind of file format to use. I have only one suggestion: consistency. Okay, two suggestions: unless otherwise specified, don't include anything other than the SOP. No bibliography or footnotes. If you quote or paraphrase someone, cite them in the text the way they do it in the average newspaper article. As Scooby says, "Ruh-roh!"
 
Now, start writing. Create something of a master SOP, or a set of master sentences for the SOPs. Some things should be in every one of them, like what your research interests are. Because length requirements are different for each program, you should work out more than one sentence or set of sentences for each thing you plan to put into more than one SOP. Have a more detailed explanation of your research interests and a more concise one. Even though this might be central and, perhaps, most important to the SOP, you don't want most of a short SOP taken up by one thing. Make these sentences do extra duties. If they can explain not only why you're into what you're into, but also why it's significant to the discipline/program, and how the program factors into it, bonus! The more functions one sentence can serve, with clear, readable logic, the more room you have in the length requirements to bring in other things. Think of this master SOP as more of a set of sentences you can hang on the individual SOP's unique structure. A flesh and skeleton metaphor can work here. You can order all SOPs at this point, you'll probably want to put research interests in the middle or toward the end, rather than in the first sentence, but the key here is that the skeleton of the individual SOP and most of its flesh will come from the needs of the program you're writing it for, not from some predetermined formula. No generically applicable, master SOP that has a few tweaks here and there.
 
Here's the thing. The SOP is one of the most important documents you'll write in your life. It's not something that should be done in a few hours, after looking at the program website and spending some time on the net searching for a how-to-write-an-SOP-guide. It takes work backed by research. The readers can tell quite easily how much research you've done on them by the way you structure and write your SOP. They can tell if you're sending out a generic SOP to several programs because it will be too general. You can't change faculty names in and out, along with a detail or two that makes it seem tailored to the program. The individual SOP should be tailored from the beginning. Some sentences won't change much, so you can pre-write them. But how they fit into each SOP, the reasoning you'll use to try to convince the adcomm that you're the best applicant, and the perspective you'll take all the way to the words you use should be done with the program in mind. It shouldn't be generic. Even if it doesn't seem noticeably generic to you, that doesn't mean that the adcomm won't notice it. They read many, many SOPs every year. People who read SOPs develop a sense about the generic, the cut and paste work.
 
How to name drop gracefully, or bring up the theory and histories and whatnot you're working with when there's only a teeny amount of space for everything? That's a bit easier than it might seem. It's not in the explanation; it's in the usage. If you can use the relevant theories and people and methodologies correctly in a sentence, you don't have to show the adcomm that you know how to use them, or how they're related, by explaining it. Trust them to have enough education to make a few connections for themselves when it comes to the discipline. Example: Novels such as Twilight exemplify how Marxist alienation can be applied to childbirth. My research interest lies in the alienation of women from the product of delivery in Modernist American fiction, such as Faulkner's Sound and the Fury. (Huh, I wonder if that would really work?) Two sentences and I've referenced theory, period, history, relevance for today, and some methodology (it's literature, not science). Use it, don't explain it.
 
If possible, have a professor you know read the SOP to your preferred school and give you some advice. They know more than most other groups of people. If not possible, your current university's writing center can help, or other people who are familiar with the field, or with writing. Your high school English teacher or your English major buddy can probably say something about your grammar, but might not be as helpful as expected. Example, in English, the convention is to speak of historical people in present tense. Shakespeare writes, "To be or not to be," because he thinks it is the question. History has kittens. Shakespeare has been dead for centuries, he can't write! Past tense! Shakespeare wrote, "To be or not to be," because thought it was the question. Someone in the field is preferable!
 
Finally, a word about my real credentials. The adcomm is going to do to your application what you've just done with this post. They are going to judge your credentials (your ethos, trustworthiness, veracity, credibility, knowledge, and so on) based on the impressions they get of you from what you've written. So, be knowledgeable about you, your field, and the program, and use that knowledge well.

First, my credentials. Well. I can spell my own name, though I don't usually know exactly how old I am. I'm within a year or two, but I'm usually wrong until I've done some subtraction. I teach composition and like to write calculus equations on the board when I take classes in poetry writing. But, here's my real credentials: consider what is written herein in conjunction with what the various instructions on SOPs that you've read have said, with the requirements the program you are applying to has put forth, and with your own experience as a writer.

I'm not promising that you'll get in to any place you desire, or that there is any one best thing to put in the SOP to get noticed. That would be totally impossible.

You can't change faculty names in and out, along with a detail or two that makes it seem tailored to the program. The individual SOP should be tailored from the beginning. Some sentences won't change much, so you can pre-write them. But how they fit into each SOP, the reasoning you'll use to try to convince the adcomm that you're the best applicant, and the perspective you'll take all the way to the words you use should be done with the program in mind. It shouldn't be generic. Even if it doesn't seem noticeably generic to you, that doesn't mean that the adcomm won't notice it. They read many, many SOPs every year. People who read SOPs develop a sense about the generic, the cut and paste work.
 
How to name drop gracefully, or bring up the theory and histories and whatnot you're working with when there's only a teeny amount of space for everything? That's a bit easier than it might seem. It's not in the explanation; it's in the usage. If you can use the relevant theories and people and methodologies correctly in a sentence, you don't have to show the adcomm that you know how to use them, or how they're related, by explaining it. Trust them to have enough education to make a few connections for themselves when it comes to the discipline. Example: Novels such as Twilight exemplify how Marxist alienation can be applied to childbirth. My research interest lies in the alienation of women from the product of delivery in Modernist American fiction, such as Faulkner's Sound and the Fury. (Huh, I wonder if that would really work?) Two sentences and I've referenced theory, period, history, relevance for today, and some methodology (it's literature, not science). Use it, don't explain it.
 
If possible, have a professor you know read the SOP to your preferred school and give you some advice. They know more than most other groups of people. If not possible, your current university's writing center can help, or other people who are familiar with the field, or with writing. Your high school English teacher or your English major buddy can probably say something about your grammar, but might not be as helpful as expected. Example, in English, the convention is to speak of historical people in present tense. Shakespeare writes, "To be or not to be," because he thinks it is the question. History has kittens. Shakespeare has been dead for centuries, he can't write! Past tense! Shakespeare wrote, "To be or not to be," because thought it was the question. Someone in the field is preferable!
 
Finally, a word about my real credentials. The adcomm is going to do to your application what you've just done with this post. They are going to judge your credentials (your ethos, trustworthiness, veracity, credibility, knowledge, and so on) based on the impressions they get of you from what you've written. So, be knowledgeable about you, your field, and the program, and use that knowledge well.

First, my credentials. Well. I can spell my own name, though I don't usually know exactly how old I am. I'm within a year or two, but I'm usually wrong until I've done some subtraction. I teach composition and like to write calculus equations on the board when I take classes in poetry writing. But, here's my real credentials: consider what is written herein in conjunction with what the various instructions on SOPs that you've read have said, with the requirements the program you are applying to has put forth, and with your own experience as a writer. Do you think I know what I'm talking about? Should you pay any attention to it? Is any of it useful?
 
Second, I'm not going to give you a formula for what the standard SOP is like, or a list of things the various thousands of admissions committees will be looking for. There are plenty of prescriptions on the internet, many of them written by professors who have presumably gotten sick of badly written SOPs.
 
Third, I'm not promising that SOP writing be easier after this. It'll be harder, actually. I'm not promising that you'll get in to any place you desire, or that there is any one best thing to put in the SOP to get noticed. That would be totally impossible. Each discipline has its own needs and values, as does each university, each department, and each faculty member on the admissions committee (adcomm). There is no one size and it doesn't fit most, let alone all. There are conventions (use Standard English, for one), but other than include your research interests, I won't advocate that any one thing is strictly necessary. I leave that up to the more knowledgeable.
 
The advice:
 
First thing is to deeply understand that you should write an SOP for each program. Most people take this to mean write one master SOP and then tweak as necessary to make the one SOP applicable to each university (U of A becomes U of B, Professor X becomes Professor Y). You can do that. You can be very successful doing that. You most likely, really shouldn't do it.
 
The next thing to understand is the SOP's purpose. Why do the adcomms want to see SOPs? Shouldn't transcripts, letters of recommendation, and a writing sample do it? After all, transcripts and samples show the actual scholarship and the letters verify it. The SOP isn't for showing scholarship off, or to act like a resume, or anything. So why do the adcomms want an SOP? Why are the SOPs one of those make-it-or-fail things? What is the SOP's purpose? In job hunting terms, the SOP is like a cover letter. The cover letter is to make clear connections between the resume and the job ad. For you, its primary purpose is to make the adcomm offer you admission with full funding. For the adcomm, its primary purpose is to help them see how you would fit into their program (make connections between their program and you). By fit, I mean do they have faculty (or enough faculty) in your area of research interest that can advise, mentor, supervise, and/or committee you through the program to get your degree? Do you have the kind of understanding of the discipline, your research interests, and their program that would make you successful? Do they have something to teach you? Offer you? What can you offer them? They want to brag on you as much as you want to brag about them. If they offer you admission, will you be a good scholar? A good student? Here is the most basic question the SOP should answer: What is it about you that makes you a better prospect than everyone else who's applying?
 
Understanding the SOP's purpose, in practical terms, means that you will know what to put into it and what to leave out of it. And how to phrase it.
 
So, with the purpose in mind, there comes the question: what should you put into it and leave out of it? What format should you use? (MLA? APA? Is footnoting okay?! What about citation?!) Should I stick in a personal story that everyone seems to recommend, except for the half that don't? My research interests? The story about why I got on F in that one, very important class? I'm not going to answer those questions because I can't. Every discipline and department is different. I will give you an answer you won't like: research. Find out the requirements each program you're interested in has for the SOP, think of the SOP's purpose: and now research.
 
Research is one of the basic keys to writing an SOP. It's no different than the writing sample you'll be including in your application packet. For each program you apply to, do some research. How much research you need to do depends on a lot of things, the least of which is your personality. More research does not automatically mean a better SOP. Less research doesn't automatically mean a better one, either. What makes the right amount of research? The ability to craft an SOP that is specific for the program that you're getting into. Here's some ideas (not an exhaustive, inclusive list of what to do) on what to research:
The program itself. Look at the recent graduates and, if possible, read their theses and/or dissertations, at least in part. The acknowledgements can give you an idea about the program's culture. The introduction can give you an idea about what kind of scholarship the program produces and expects. It will also, and this is very important, give you an idea as to how the program uses language. If you speak to them in their own language, that helps your case. You've likely done this, if not, seriously, you should have done this. Look at the program's website and read it all. What kind of classes are offered for both undergrad and grad. Who are the faculty, the tenured, the assistant, the visiting, the emeritus, and the graduate students. What kind of ties to the community (both academic and their local town) do they like to talk about? Do they talk about how their graduate students are working with community partners? Do they host conferences? What happened at the last one? This gives you a taste of the program's culture. The faculty. All of them that might be on the adcomm and the ones that are relevant or somewhat relevant to your interests. Crack open JSTOR etc. and search for recent faculty publications. If you're basing your interest on a faculty member on the interests they've got listed on the site and a reference to them in an article from a decade ago, or worse, only their reputation, you don't have a strong basis to establish clear reasons why they have anything to offer you. Read their recent publications, see who they name drop in terms of theory, other faculty, and so on. Make a list of what each faculty member can offer you in terms of research, not just the ones that are directly related to it. If you're into studying apples, but Dr. V works with oranges, think about how Dr. V's work might help you out. Take notes when you research. Each program has a bunch of people, and you're likely applying to multiple programs. It's easier to refer to notes than to go back and look it up all over again. What's happening in the field with your current research interests, if necessary. This is so you can situate your research interests in the discipline, and then situation your research interests in the program. You can just tell them what you're research interests are and leave the situating to them, but you can lose that chance to sell yourself as the best amongst the rest. Research you. Yup. You. Scribble out some lists or paragraphs or whatever that inventories you. Who are your influences? Who are the theorists you keep coming back to? Who are the theorists you loathe, mock, and/or ridicule? What are your research interests in general and specifically and anywhere in between? Some SOPs will need to be more general, some will need to be more specific. Length restrictions, what you found out about the program, the faculty, the state of the discipline, and so on, can alter this for you. What kind of scholar are you? Student? What's the difference? How do you manage your time? Stress? Health? Do you expect to bring your dog? Do you have health issues? Do you have any academic things that are a negative? If you do, how negative are they? It's easy to see that as an either it's entirely bad, or it's somewhere in the huge good category, but some things are negatives that need to be addressed for certain programs, while other negatives can be ignored, or you should discuss with the one relevant letter writer so they can address it. While Sam ultimately received a C in the Research Methods course, the grade doesn't reflect the actual scholarship as Sam fell ill during the mid-term and consequently failed it; my course policies do not permit re-taking the test. What are the good things about you? Not just the grades, awards, publications, and presentations, but also the character traits. What are you weaknesses? Don't do the job interview baloney, my greatest weakness is my perfectionism. Of course, the important, probably ought to be on the SOP questions: why grad school? What will you do with the degree you want? Why are into the research you're into? Why that particular school? Why are you worth admission and funding?
 
Research the assistanceships. Some SOPs will want you to write a bit about teaching or research with assistanceships in mind. So, do a bit of research on what these entail in the programs you're looking at. What do they do and how do they get it? Have you done assistanceships in the past? If so, what were they like? Do you have a teaching philosophy? If not, make one. Have you done anything that can be discussed in terms of the assistanceship? I taught kung-fu to white belt children, so I have teaching experience. I was part of the state herpetological society and went out to help them with their field counts twice a year. I learned that licking petrie dishes is always a bad idea, no matter how much they resemble pistachio ice cream.
 
Research SOPs. You're doing that, right? Go on to forums (like this one) and read the SOPs people have posted and then read the responses. Look particularly at SOPs in your discipline or related disciplines. Psychology might look at other social sciences. Physics might tell the joke about the Higgs Boson and Sunday mass. Bear in mind that the people responding to and/or criticizing the posted SOPs are likely not on an adcomm. Some have been  or will be, but it's not likely they'll be on the adcomm you're hoping will like you best. However, you can start to get a sense of what SOPs are like. What format is it in? Does yours look like everyone else's? Do you have the exact same opening sentence as half of the people hoping to get into a program in your discipline? I've always wanted to be a librarian since those wonderful, summer days I spent in my (relative of choice)'s home library. 
 
So, to take stock. First, understand the purpose. Second, research. A lot. Let the purpose of the SOP guide your research efforts.
 
Next, get the specific requirements for the SOP from each program. Make a list of similarities. If they all ask for a statement of your research interest, score! One sentence fits most! Most of them will be of different lengths and will have different ideas of what specific information they want. Most won't tell you enough, aside from length and one or two "should have" things. They mostly won't tell you if you should use APA or if you should footnote, or how to format it. Single space? Double space? They will tell you whether it should be on paper or what kind of file format to use. I have only one suggestion: consistency. Okay, two suggestions: unless otherwise specified, don't include anything other than the SOP. No bibliography or footnotes. If you quote or paraphrase someone, cite them in the text the way they do it in the average newspaper article. As Scooby says, "Ruh-roh!"
 
Now, start writing. Create something of a master SOP, or a set of master sentences for the SOPs. Some things should be in every one of them, like what your research interests are. Because length requirements are different for each program, you should work out more than one sentence or set of sentences for each thing you plan to put into more than one SOP. Have a more detailed explanation of your research interests and a more concise one. Even though this might be central and, perhaps, most important to the SOP, you don't want most of a short SOP taken up by one thing. Make these sentences do extra duties. If they can explain not only why you're into what you're into, but also why it's significant to the discipline/program, and how the program factors into it, bonus! The more functions one sentence can serve, with clear, readable logic, the more room you have in the length requirements to bring in other things. Think of this master SOP as more of a set of sentences you can hang on the individual SOP's unique structure. A flesh and skeleton metaphor can work here. You can order all SOPs at this point, you'll probably want to put research interests in the middle or toward the end, rather than in the first sentence, but the key here is that the skeleton of the individual SOP and most of its flesh will come from the needs of the program you're writing it for, not from some predetermined formula. No generically applicable, master SOP that has a few tweaks here and there.
 
Here's the thing. The SOP is one of the most important documents you'll write in your life. It's not something that should be done in a few hours, after looking at the program website and spending some time on the net searching for a how-to-write-an-SOP-guide. It takes work backed by research. The readers can tell quite easily how much research you've done on them by the way you structure and write your SOP. They can tell if you're sending out a generic SOP to several programs because it will be too general. You can't change faculty names in and out, along with a detail or two that makes it seem tailored to the program. The individual SOP should be tailored from the beginning. Some sentences won't change much, so you can pre-write them. But how they fit into each SOP, the reasoning you'll use to try to convince the adcomm that you're the best applicant, and the perspective you'll take all the way to the words you use should be done with the program in mind. It shouldn't be generic. Even if it doesn't seem noticeably generic to you, that doesn't mean that the adcomm won't notice it. They read many, many SOPs every year. People who read SOPs develop a sense about the generic, the cut and paste work.

It's not in the explanation; it's in the usage.

Trust them to have enough education to make a few connections for themselves when it comes to the discipline. Example: Novels such as Twilight exemplify how Marxist alienation can be applied to childbirth.

Finally, a word about my real credentials. The adcomm is going to do to your application what you've just done with this post. They are going to judge your credentials (your ethos, trustworthiness, veracity, credibility, knowledge, and so on) based on the impressions they get of you from what you've written. So, be knowledgeable about you, your field, and the program, and use that knowledge well.

I did my UG in a small Div II university (7,100 average total enrollment). One of the Gen Ed requirements gives students a choice between Intro to Sociology or Intro to Women's Studies. I took both because my first degree is in sociology. Anyway, the course had an enrollment of 30 and 11 of those spots were taken by men. Only two were left after the first week and only one stayed the course. I'm pretty sure it's because his girlfriend was involved.
 
Women's studies is very uncomfortable for men, I think. It examines patriarchy and finds it abusive. It points out male privilege, privilege that many men took for granted as normal or a right, something everyone experiences. When they're forced to see the opposite point of view, it feels like a personal attack, perhaps even an examination of all the ways in which men are bullies and women are victims of that bullying. I also think that it's says a lot about your women's studies professors that they did not alienate you. I've been in a few classes that were either specifically women's studies or were run as if they were feminist studies. There was a lack of sensitivity to the men in the class; there was a sense that there was an expectation that men would just have to suck it up and get what it feels like to be the second class citizen for a change, that as beneficiaries of systemic privilege, they had no room to complain about feeling disenfranchised, powerless, and devalued. I think that's wrong because it just serves to alienate men from the subject---not women's studies, but the subject itself. It alienates men from embracing the feminism they already participate in. (Few men believe in unequal pay anymore, or that women should not work, or should not participate in all parts of civil life.) There is a place for anyone in women's studies. I don't think a field of study can be legitimate if there is a restriction on who can study it based on gender, sexuality, ethnicity, or social status. I also think that there's a lack of men in women's studies because of that sense of alienation men get from the very beginning. I also think that women's studies would be a stronger discipline if it did have men in it on a broader scale. Men are fully capable of understanding, researching, and adding knowledge to the field. Women's studies should no more be a female privilege than any other field should be a male privilege. Maybe that makes me weird or wrong in some people's eyes, but there is (should) be a place for men in women's studies. Women's studies instructors need to develop a method of teaching the subject without alienating men from it. There's a difference from making people uncomfortable (good teaching should challenge beliefs) and making people feel that the curriculum finds personal fault with them and that everyone in class blames them for things they have no control over.
 
Full disclosure: I characterize myself as a humanist, but that still means I'm a feminist. I'm also a masculinist. It's telling that spellcheck doesn't recognize the term masculinist, but it picks out feminist just fine. The key is that neither gender should have hegemony.

First, my credentials. Well. I can spell my own name, though I don't usually know exactly how old I am. I'm within a year or two, but I'm usually wrong until I've done some subtraction. I teach composition and like to write calculus equations on the board when I take classes in poetry writing.

Now, start writing. Create something of a master SOP, or a set of master sentences for the SOPs. Some things should be in every one of them, like what your research interests are. Because length requirements are different for each program, you should work out more than one sentence or set of sentences for each thing you plan to put into more than one SOP. Have a more detailed explanation of your research interests and a more concise one. Even though this might be central and, perhaps, most important to the SOP, you don't want most of a short SOP taken up by one thing. Make these sentences do extra duties. If they can explain not only why you're into what you're into, but also why it's significant to the discipline/program, and how the program factors into it, bonus! The more functions one sentence can serve, with clear, readable logic, the more room you have in the length requirements to bring in other things. Think of this master SOP as more of a set of sentences you can hang on the individual SOP's unique structure. A flesh and skeleton metaphor can work here. You can order all SOPs at this point, you'll probably want to put research interests in the middle or toward the end, rather than in the first sentence, but the key here is that the skeleton of the individual SOP and most of its flesh will come from the needs of the program you're writing it for, not from some predetermined formula. No generically applicable, master SOP that has a few tweaks here and there.
 
Here's the thing. The SOP is one of the most important documents you'll write in your life. It's not something that should be done in a few hours, after looking at the program website and spending some time on the net searching for a how-to-write-an-SOP-guide. It takes work backed by research. The readers can tell quite easily how much research you've done on them by the way you structure and write your SOP. They can tell if you're sending out a generic SOP to several programs because it will be too general. You can't change faculty names in and out, along with a detail or two that makes it seem tailored to the program. The individual SOP should be tailored from the beginning. Some sentences won't change much, so you can pre-write them. But how they fit into each SOP, the reasoning you'll use to try to convince the adcomm that you're the best applicant, and the perspective you'll take all the way to the words you use should be done with the program in mind. It shouldn't be generic. Even if it doesn't seem noticeably generic to you, that doesn't mean that the adcomm won't notice it. They read many, many SOPs every year. People who read SOPs develop a sense about the generic, the cut and paste work.
 
How to name drop gracefully, or bring up the theory and histories and whatnot you're working with when there's only a teeny amount of space for everything? That's a bit easier than it might seem. It's not in the explanation; it's in the usage. If you can use the relevant theories and people and methodologies correctly in a sentence, you don't have to show the adcomm that you know how to use them, or how they're related, by explaining it. Trust them to have enough education to make a few connections for themselves when it comes to the discipline. Example: Novels such as Twilight exemplify how Marxist alienation can be applied to childbirth. My research interest lies in the alienation of women from the product of delivery in Modernist American fiction, such as Faulkner's Sound and the Fury. (Huh, I wonder if that would really work?) Two sentences and I've referenced theory, period, history, relevance for today, and some methodology (it's literature, not science). Use it, don't explain it.
 
If possible, have a professor you know read the SOP to your preferred school and give you some advice. They know more than most other groups of people. If not possible, your current university's writing center can help, or other people who are familiar with the field, or with writing. Your high school English teacher or your English major buddy can probably say something about your grammar, but might not be as helpful as expected. Example, in English, the convention is to speak of historical people in present tense. Shakespeare writes, "To be or not to be," because he thinks it is the question. History has kittens. Shakespeare has been dead for centuries, he can't write! Past tense! Shakespeare wrote, "To be or not to be," because thought it was the question. Someone in the field is preferable!
 
Finally, a word about my real credentials. The adcomm is going to do to your application what you've just done with this post. They are going to judge your credentials (your ethos, trustworthiness, veracity, credibility, knowledge, and so on) based on the impressions they get of you from what you've written. So, be knowledgeable about you, your field, and the program, and use that knowledge well.

First, my credentials. Well. I can spell my own name, though I don't usually know exactly how old I am. I'm within a year or two, but I'm usually wrong until I've done some subtraction. I teach composition and like to write calculus equations on the board when I take classes in poetry writing. But, here's my real credentials: consider what is written herein in conjunction with what the various instructions on SOPs that you've read have said, with the requirements the program you are applying to has put forth, and with your own experience as a writer. Do you think I know what I'm talking about? Should you pay any attention to it? Is any of it useful?
 
Second, I'm not going to give you a formula for what the standard SOP is like, or a list of things the various thousands of admissions committees will be looking for. There are plenty of prescriptions on the internet, many of them written by professors who have presumably gotten sick of badly written SOPs.
 
Third, I'm not promising that SOP writing be easier after this. It'll be harder, actually. I'm not promising that you'll get in to any place you desire, or that there is any one best thing to put in the SOP to get noticed. That would be totally impossible. Each discipline has its own needs and values, as does each university, each department, and each faculty member on the admissions committee (adcomm). There is no one size and it doesn't fit most, let alone all. There are conventions (use Standard English, for one), but other than include your research interests, I won't advocate that any one thing is strictly necessary. I leave that up to the more knowledgeable.
 
The advice:
 
First thing is to deeply understand that you should write an SOP for each program. Most people take this to mean write one master SOP and then tweak as necessary to make the one SOP applicable to each university (U of A becomes U of B, Professor X becomes Professor Y). You can do that. You can be very successful doing that. You most likely, really shouldn't do it.
 
The next thing to understand is the SOP's purpose. Why do the adcomms want to see SOPs? Shouldn't transcripts, letters of recommendation, and a writing sample do it? After all, transcripts and samples show the actual scholarship and the letters verify it. The SOP isn't for showing scholarship off, or to act like a resume, or anything. So why do the adcomms want an SOP? Why are the SOPs one of those make-it-or-fail things? What is the SOP's purpose? In job hunting terms, the SOP is like a cover letter. The cover letter is to make clear connections between the resume and the job ad. For you, its primary purpose is to make the adcomm offer you admission with full funding. For the adcomm, its primary purpose is to help them see how you would fit into their program (make connections between their program and you). By fit, I mean do they have faculty (or enough faculty) in your area of research interest that can advise, mentor, supervise, and/or committee you through the program to get your degree? Do you have the kind of understanding of the discipline, your research interests, and their program that would make you successful? Do they have something to teach you? Offer you? What can you offer them? They want to brag on you as much as you want to brag about them. If they offer you admission, will you be a good scholar? A good student? Here is the most basic question the SOP should answer: What is it about you that makes you a better prospect than everyone else who's applying?
 
Understanding the SOP's purpose, in practical terms, means that you will know what to put into it and what to leave out of it. And how to phrase it.
 
So, with the purpose in mind, there comes the question: what should you put into it and leave out of it? What format should you use? (MLA? APA? Is footnoting okay?! What about citation?!) Should I stick in a personal story that everyone seems to recommend, except for the half that don't? My research interests? The story about why I got on F in that one, very important class? I'm not going to answer those questions because I can't. Every discipline and department is different. I will give you an answer you won't like: research. Find out the requirements each program you're interested in has for the SOP, think of the SOP's purpose: and now research.
 
Research is one of the basic keys to writing an SOP. It's no different than the writing sample you'll be including in your application packet. For each program you apply to, do some research. How much research you need to do depends on a lot of things, the least of which is your personality. More research does not automatically mean a better SOP. Less research doesn't automatically mean a better one, either. What makes the right amount of research? The ability to craft an SOP that is specific for the program that you're getting into. Here's some ideas (not an exhaustive, inclusive list of what to do) on what to research:
The program itself. Look at the recent graduates and, if possible, read their theses and/or dissertations, at least in part. The acknowledgements can give you an idea about the program's culture. The introduction can give you an idea about what kind of scholarship the program produces and expects. It will also, and this is very important, give you an idea as to how the program uses language. If you speak to them in their own language, that helps your case. You've likely done this, if not, seriously, you should have done this. Look at the program's website and read it all. What kind of classes are offered for both undergrad and grad. Who are the faculty, the tenured, the assistant, the visiting, the emeritus, and the graduate students. What kind of ties to the community (both academic and their local town) do they like to talk about? Do they talk about how their graduate students are working with community partners? Do they host conferences? What happened at the last one? This gives you a taste of the program's culture. The faculty. All of them that might be on the adcomm and the ones that are relevant or somewhat relevant to your interests. Crack open JSTOR etc. and search for recent faculty publications. If you're basing your interest on a faculty member on the interests they've got listed on the site and a reference to them in an article from a decade ago, or worse, only their reputation, you don't have a strong basis to establish clear reasons why they have anything to offer you. Read their recent publications, see who they name drop in terms of theory, other faculty, and so on. Make a list of what each faculty member can offer you in terms of research, not just the ones that are directly related to it. If you're into studying apples, but Dr. V works with oranges, think about how Dr. V's work might help you out. Take notes when you research. Each program has a bunch of people, and you're likely applying to multiple programs. It's easier to refer to notes than to go back and look it up all over again. What's happening in the field with your current research interests, if necessary. This is so you can situate your research interests in the discipline, and then situation your research interests in the program. You can just tell them what you're research interests are and leave the situating to them, but you can lose that chance to sell yourself as the best amongst the rest. Research you. Yup. You. Scribble out some lists or paragraphs or whatever that inventories you. Who are your influences? Who are the theorists you keep coming back to? Who are the theorists you loathe, mock, and/or ridicule? What are your research interests in general and specifically and anywhere in between? Some SOPs will need to be more general, some will need to be more specific. Length restrictions, what you found out about the program, the faculty, the state of the discipline, and so on, can alter this for you. What kind of scholar are you? Student? What's the difference? How do you manage your time? Stress? Health? Do you expect to bring your dog? Do you have health issues? Do you have any academic things that are a negative? If you do, how negative are they? It's easy to see that as an either it's entirely bad, or it's somewhere in the huge good category, but some things are negatives that need to be addressed for certain programs, while other negatives can be ignored, or you should discuss with the one relevant letter writer so they can address it. While Sam ultimately received a C in the Research Methods course, the grade doesn't reflect the actual scholarship as Sam fell ill during the mid-term and consequently failed it; my course policies do not permit re-taking the test. What are the good things about you? Not just the grades, awards, publications, and presentations, but also the character traits. What are you weaknesses? Don't do the job interview baloney, my greatest weakness is my perfectionism. Of course, the important, probably ought to be on the SOP questions: why grad school? What will you do with the degree you want? Why are into the research you're into? Why that particular school? Why are you worth admission and funding?
 
Research the assistanceships. Some SOPs will want you to write a bit about teaching or research with assistanceships in mind. So, do a bit of research on what these entail in the programs you're looking at. What do they do and how do they get it? Have you done assistanceships in the past? If so, what were they like? Do you have a teaching philosophy? If not, make one. Have you done anything that can be discussed in terms of the assistanceship? I taught kung-fu to white belt children, so I have teaching experience. I was part of the state herpetological society and went out to help them with their field counts twice a year. I learned that licking petrie dishes is always a bad idea, no matter how much they resemble pistachio ice cream.
 
Research SOPs. You're doing that, right? Go on to forums (like this one) and read the SOPs people have posted and then read the responses. Look particularly at SOPs in your discipline or related disciplines. Psychology might look at other social sciences. Physics might tell the joke about the Higgs Boson and Sunday mass. Bear in mind that the people responding to and/or criticizing the posted SOPs are likely not on an adcomm. Some have been  or will be, but it's not likely they'll be on the adcomm you're hoping will like you best. However, you can start to get a sense of what SOPs are like. What format is it in? Does yours look like everyone else's? Do you have the exact same opening sentence as half of the people hoping to get into a program in your discipline? I've always wanted to be a librarian since those wonderful, summer days I spent in my (relative of choice)'s home library. 
 
So, to take stock. First, understand the purpose. Second, research. A lot. Let the purpose of the SOP guide your research efforts.
 
Next, get the specific requirements for the SOP from each program. Make a list of similarities. If they all ask for a statement of your research interest, score! One sentence fits most! Most of them will be of different lengths and will have different ideas of what specific information they want. Most won't tell you enough, aside from length and one or two "should have" things. They mostly won't tell you if you should use APA or if you should footnote, or how to format it. Single space? Double space? They will tell you whether it should be on paper or what kind of file format to use. I have only one suggestion: consistency. Okay, two suggestions: unless otherwise specified, don't include anything other than the SOP. No bibliography or footnotes. If you quote or paraphrase someone, cite them in the text the way they do it in the average newspaper article. As Scooby says, "Ruh-roh!"
 
Now, start writing. Create something of a master SOP, or a set of master sentences for the SOPs. Some things should be in every one of them, like what your research interests are. Because length requirements are different for each program, you should work out more than one sentence or set of sentences for each thing you plan to put into more than one SOP. Have a more detailed explanation of your research interests and a more concise one. Even though this might be central and, perhaps, most important to the SOP, you don't want most of a short SOP taken up by one thing. Make these sentences do extra duties. If they can explain not only why you're into what you're into, but also why it's significant to the discipline/program, and how the program factors into it, bonus!

You can order all SOPs at this point, you'll probably want to put research interests in the middle or toward the end, rather than in the first sentence, but the key here is that the skeleton of the individual SOP and most of its flesh will come from the needs of the program you're writing it for, not from some predetermined formula. No generically applicable, master SOP that has a few tweaks here and there.
 
Here's the thing. The SOP is one of the most important documents you'll write in your life. It's not something that should be done in a few hours, after looking at the program website and spending some time on the net searching for a how-to-write-an-SOP-guide. It takes work backed by research. The readers can tell quite easily how much research you've done on them by the way you structure and write your SOP. They can tell if you're sending out a generic SOP to several programs because it will be too general. You can't change faculty names in and out, along with a detail or two that makes it seem tailored to the program. The individual SOP should be tailored from the beginning. Some sentences won't change much, so you can pre-write them. But how they fit into each SOP, the reasoning you'll use to try to convince the adcomm that you're the best applicant, and the perspective you'll take all the way to the words you use should be done with the program in mind. It shouldn't be generic. Even if it doesn't seem noticeably generic to you, that doesn't mean that the adcomm won't notice it. They read many, many SOPs every year. People who read SOPs develop a sense about the generic, the cut and paste work.
 
How to name drop gracefully, or bring up the theory and histories and whatnot you're working with when there's only a teeny amount of space for everything? That's a bit easier than it might seem. It's not in the explanation; it's in the usage. If you can use the relevant theories and people and methodologies correctly in a sentence, you don't have to show the adcomm that you know how to use them, or how they're related, by explaining it. Trust them to have enough education to make a few connections for themselves when it comes to the discipline. Example: Novels such as Twilight exemplify how Marxist alienation can be applied to childbirth. My research interest lies in the alienation of women from the product of delivery in Modernist American fiction, such as Faulkner's Sound and the Fury. (Huh, I wonder if that would really work?) Two sentences and I've referenced theory, period, history, relevance for today, and some methodology (it's literature, not science). Use it, don't explain it.
 
If possible, have a professor you know read the SOP to your preferred school and give you some advice. They know more than most other groups of people. If not possible, your current university's writing center can help, or other people who are familiar with the field, or with writing. Your high school English teacher or your English major buddy can probably say something about your grammar, but might not be as helpful as expected. Example, in English, the convention is to speak of historical people in present tense. Shakespeare writes, "To be or not to be," because he thinks it is the question. History has kittens. Shakespeare has been dead for centuries, he can't write! Past tense! Shakespeare wrote, "To be or not to be," because thought it was the question. Someone in the field is preferable!
 
Finally, a word about my real credentials. The adcomm is going to do to your application what you've just done with this post. They are going to judge your credentials (your ethos, trustworthiness, veracity, credibility, knowledge, and so on) based on the impressions they get of you from what you've written. So, be knowledgeable about you, your field, and the program, and use that knowledge well.

First, my credentials. Well. I can spell my own name, though I don't usually know exactly how old I am. I'm within a year or two, but I'm usually wrong until I've done some subtraction. I teach composition and like to write calculus equations on the board when I take classes in poetry writing. But, here's my real credentials: consider what is written herein in conjunction with what the various instructions on SOPs that you've read have said, with the requirements the program you are applying to has put forth, and with your own experience as a writer. Do you think I know what I'm talking about? Should you pay any attention to it? Is any of it useful?
 
Second, I'm not going to give you a formula for what the standard SOP is like, or a list of things the various thousands of admissions committees will be looking for. There are plenty of prescriptions on the internet, many of them written by professors who have presumably gotten sick of badly written SOPs.
 
Third, I'm not promising that SOP writing be easier after this. It'll be harder, actually. I'm not promising that you'll get in to any place you desire, or that there is any one best thing to put in the SOP to get noticed. That would be totally impossible. Each discipline has its own needs and values, as does each university, each department, and each faculty member on the admissions committee (adcomm). There is no one size and it doesn't fit most, let alone all. There are conventions (use Standard English, for one), but other than include your research interests, I won't advocate that any one thing is strictly necessary. I leave that up to the more knowledgeable.
 
The advice:
 
First thing is to deeply understand that you should write an SOP for each program. Most people take this to mean write one master SOP and then tweak as necessary to make the one SOP applicable to each university (U of A becomes U of B, Professor X becomes Professor Y). You can do that. You can be very successful doing that. You most likely, really shouldn't do it.
 
The next thing to understand is the SOP's purpose. Why do the adcomms want to see SOPs? Shouldn't transcripts, letters of recommendation, and a writing sample do it? After all, transcripts and samples show the actual scholarship and the letters verify it. The SOP isn't for showing scholarship off, or to act like a resume, or anything. So why do the adcomms want an SOP? Why are the SOPs one of those make-it-or-fail things? What is the SOP's purpose? In job hunting terms, the SOP is like a cover letter. The cover letter is to make clear connections between the resume and the job ad. For you, its primary purpose is to make the adcomm offer you admission with full funding. For the adcomm, its primary purpose is to help them see how you would fit into their program (make connections between their program and you). By fit, I mean do they have faculty (or enough faculty) in your area of research interest that can advise, mentor, supervise, and/or committee you through the program to get your degree? Do you have the kind of understanding of the discipline, your research interests, and their program that would make you successful? Do they have something to teach you? Offer you? What can you offer them? They want to brag on you as much as you want to brag about them. If they offer you admission, will you be a good scholar? A good student? Here is the most basic question the SOP should answer: What is it about you that makes you a better prospect than everyone else who's applying?
 
Understanding the SOP's purpose, in practical terms, means that you will know what to put into it and what to leave out of it. And how to phrase it.
 
So, with the purpose in mind, there comes the question: what should you put into it and leave out of it? What format should you use? (MLA? APA? Is footnoting okay?! What about citation?!) Should I stick in a personal story that everyone seems to recommend, except for the half that don't? My research interests? The story about why I got on F in that one, very important class? I'm not going to answer those questions because I can't. Every discipline and department is different. I will give you an answer you won't like: research. Find out the requirements each program you're interested in has for the SOP, think of the SOP's purpose: and now research.
 
Research is one of the basic keys to writing an SOP. It's no different than the writing sample you'll be including in your application packet. For each program you apply to, do some research. How much research you need to do depends on a lot of things, the least of which is your personality. More research does not automatically mean a better SOP. Less research doesn't automatically mean a better one, either. What makes the right amount of research? The ability to craft an SOP that is specific for the program that you're getting into. Here's some ideas (not an exhaustive, inclusive list of what to do) on what to research:
The program itself. Look at the recent graduates and, if possible, read their theses and/or dissertations, at least in part. The acknowledgements can give you an idea about the program's culture. The introduction can give you an idea about what kind of scholarship the program produces and expects. It will also, and this is very important, give you an idea as to how the program uses language. If you speak to them in their own language, that helps your case. You've likely done this, if not, seriously, you should have done this. Look at the program's website and read it all. What kind of classes are offered for both undergrad and grad. Who are the faculty, the tenured, the assistant, the visiting, the emeritus, and the graduate students. What kind of ties to the community (both academic and their local town) do they like to talk about? Do they talk about how their graduate students are working with community partners? Do they host conferences? What happened at the last one? This gives you a taste of the program's culture. The faculty. All of them that might be on the adcomm and the ones that are relevant or somewhat relevant to your interests. Crack open JSTOR etc. and search for recent faculty publications. If you're basing your interest on a faculty member on the interests they've got listed on the site and a reference to them in an article from a decade ago, or worse, only their reputation, you don't have a strong basis to establish clear reasons why they have anything to offer you. Read their recent publications, see who they name drop in terms of theory, other faculty, and so on. Make a list of what each faculty member can offer you in terms of research, not just the ones that are directly related to it. If you're into studying apples, but Dr. V works with oranges, think about how Dr. V's work might help you out. Take notes when you research. Each program has a bunch of people, and you're likely applying to multiple programs. It's easier to refer to notes than to go back and look it up all over again. What's happening in the field with your current research interests, if necessary. This is so you can situate your research interests in the discipline, and then situation your research interests in the program. You can just tell them what you're research interests are and leave the situating to them, but you can lose that chance to sell yourself as the best amongst the rest. Research you. Yup. You. Scribble out some lists or paragraphs or whatever that inventories you. Who are your influences? Who are the theorists you keep coming back to? Who are the theorists you loathe, mock, and/or ridicule? What are your research interests in general and specifically and anywhere in between? Some SOPs will need to be more general, some will need to be more specific. Length restrictions, what you found out about the program, the faculty, the state of the discipline, and so on, can alter this for you. What kind of scholar are you? Student? What's the difference? How do you manage your time? Stress? Health? Do you expect to bring your dog? Do you have health issues? Do you have any academic things that are a negative? If you do, how negative are they? It's easy to see that as an either it's entirely bad, or it's somewhere in the huge good category, but some things are negatives that need to be addressed for certain programs, while other negatives can be ignored, or you should discuss with the one relevant letter writer so they can address it. While Sam ultimately received a C in the Research Methods course, the grade doesn't reflect the actual scholarship as Sam fell ill during the mid-term and consequently failed it; my course policies do not permit re-taking the test. What are the good things about you? Not just the grades, awards, publications, and presentations, but also the character traits. What are you weaknesses? Don't do the job interview baloney, my greatest weakness is my perfectionism. Of course, the important, probably ought to be on the SOP questions: why grad school? What will you do with the degree you want? Why are into the research you're into? Why that particular school? Why are you worth admission and funding?
 
Research the assistanceships. Some SOPs will want you to write a bit about teaching or research with assistanceships in mind. So, do a bit of research on what these entail in the programs you're looking at. What do they do and how do they get it? Have you done assistanceships in the past? If so, what were they like? Do you have a teaching philosophy? If not, make one. Have you done anything that can be discussed in terms of the assistanceship? I taught kung-fu to white belt children, so I have teaching experience. I was part of the state herpetological society and went out to help them with their field counts twice a year. I learned that licking petrie dishes is always a bad idea, no matter how much they resemble pistachio ice cream.
 
Research SOPs. You're doing that, right? Go on to forums (like this one) and read the SOPs people have posted and then read the responses. Look particularly at SOPs in your discipline or related disciplines. Psychology might look at other social sciences. Physics might tell the joke about the Higgs Boson and Sunday mass. Bear in mind that the people responding to and/or criticizing the posted SOPs are likely not on an adcomm. Some have been  or will be, but it's not likely they'll be on the adcomm you're hoping will like you best. However, you can start to get a sense of what SOPs are like. What format is it in? Does yours look like everyone else's? Do you have the exact same opening sentence as half of the people hoping to get into a program in your discipline? I've always wanted to be a librarian since those wonderful, summer days I spent in my (relative of choice)'s home library. 
 
So, to take stock. First, understand the purpose. Second, research. A lot. Let the purpose of the SOP guide your research efforts.
 
Next, get the specific requirements for the SOP from each program. Make a list of similarities. If they all ask for a statement of your research interest, score! One sentence fits most! Most of them will be of different lengths and will have different ideas of what specific information they want. Most won't tell you enough, aside from length and one or two "should have" things. They mostly won't tell you if you should use APA or if you should footnote, or how to format it. Single space? Double space? They will tell you whether it should be on paper or what kind of file format to use. I have only one suggestion: consistency. Okay, two suggestions: unless otherwise specified, don't include anything other than the SOP. No bibliography or footnotes. If you quote or paraphrase someone, cite them in the text the way they do it in the average newspaper article. As Scooby says, "Ruh-roh!"
 
Now, start writing. Create something of a master SOP, or a set of master sentences for the SOPs. Some things should be in every one of them, like what your research interests are. Because length requirements are different for each program, you should work out more than one sentence or set of sentences for each thing you plan to put into more than one SOP. Have a more detailed explanation of your research interests and a more concise one. Even though this might be central and, perhaps, most important to the SOP, you don't want most of a short SOP taken up by one thing. Make these sentences do extra duties. If they can explain not only why you're into what you're into, but also why it's significant to the discipline/program, and how the program factors into it, bonus! The more functions one sentence can serve, with clear, readable logic, the more room you have in the length requirements to bring in other things. Think of this master SOP as more of a set of sentences you can hang on the individual SOP's unique structure. A flesh and skeleton metaphor can work here. You can order all SOPs at this point, you'll probably want to put research interests in the middle or toward the end, rather than in the first sentence, but the key here is that the skeleton of the individual SOP and most of its flesh will come from the needs of the program you're writing it for, not from some predetermined formula.

You can't change faculty names in and out, along with a detail or two that makes it seem tailored to the program. The individual SOP should be tailored from the beginning. Some sentences won't change much, so you can pre-write them. But how they fit into each SOP, the reasoning you'll use to try to convince the adcomm that you're the best applicant, and the perspective you'll take all the way to the words you use should be done with the program in mind. It shouldn't be generic. Even if it doesn't seem noticeably generic to you, that doesn't mean that the adcomm won't notice it. They read many, many SOPs every year. People who read SOPs develop a sense about the generic, the cut and paste work.
 
How to name drop gracefully, or bring up the theory and histories and whatnot you're working with when there's only a teeny amount of space for everything? That's a bit easier than it might seem. It's not in the explanation; it's in the usage. If you can use the relevant theories and people and methodologies correctly in a sentence, you don't have to show the adcomm that you know how to use them, or how they're related, by explaining it. Trust them to have enough education to make a few connections for themselves when it comes to the discipline. Example: Novels such as Twilight exemplify how Marxist alienation can be applied to childbirth. My research interest lies in the alienation of women from the product of delivery in Modernist American fiction, such as Faulkner's Sound and the Fury. (Huh, I wonder if that would really work?) Two sentences and I've referenced theory, period, history, relevance for today, and some methodology (it's literature, not science). Use it, don't explain it.
 
If possible, have a professor you know read the SOP to your preferred school and give you some advice. They know more than most other groups of people. If not possible, your current university's writing center can help, or other people who are familiar with the field, or with writing. Your high school English teacher or your English major buddy can probably say something about your grammar, but might not be as helpful as expected. Example, in English, the convention is to speak of historical people in present tense. Shakespeare writes, "To be or not to be," because he thinks it is the question. History has kittens. Shakespeare has been dead for centuries, he can't write! Past tense! Shakespeare wrote, "To be or not to be," because thought it was the question. Someone in the field is preferable!
 
Finally, a word about my real credentials. The adcomm is going to do to your application what you've just done with this post. They are going to judge your credentials (your ethos, trustworthiness, veracity, credibility, knowledge, and so on) based on the impressions they get of you from what you've written. So, be knowledgeable about you, your field, and the program, and use that knowledge well.

First, my credentials. Well. I can spell my own name, though I don't usually know exactly how old I am. I'm within a year or two, but I'm usually wrong until I've done some subtraction. I teach composition and like to write calculus equations on the board when I take classes in poetry writing. But, here's my real credentials: consider what is written herein in conjunction with what the various instructions on SOPs that you've read have said, with the requirements the program you are applying to has put forth, and with your own experience as a writer. Do you think I know what I'm talking about? Should you pay any attention to it? Is any of it useful?
 
Second, I'm not going to give you a formula for what the standard SOP is like, or a list of things the various thousands of admissions committees will be looking for. There are plenty of prescriptions on the internet, many of them written by professors who have presumably gotten sick of badly written SOPs.
 
Third, I'm not promising that SOP writing be easier after this. It'll be harder, actually. I'm not promising that you'll get in to any place you desire, or that there is any one best thing to put in the SOP to get noticed. That would be totally impossible. Each discipline has its own needs and values, as does each university, each department, and each faculty member on the admissions committee (adcomm). There is no one size and it doesn't fit most, let alone all. There are conventions (use Standard English, for one), but other than include your research interests, I won't advocate that any one thing is strictly necessary. I leave that up to the more knowledgeable.
 
The advice:
 
First thing is to deeply understand that you should write an SOP for each program. Most people take this to mean write one master SOP and then tweak as necessary to make the one SOP applicable to each university (U of A becomes U of B, Professor X becomes Professor Y). You can do that. You can be very successful doing that. You most likely, really shouldn't do it.
 
The next thing to understand is the SOP's purpose. Why do the adcomms want to see SOPs? Shouldn't transcripts, letters of recommendation, and a writing sample do it? After all, transcripts and samples show the actual scholarship and the letters verify it. The SOP isn't for showing scholarship off, or to act like a resume, or anything. So why do the adcomms want an SOP? Why are the SOPs one of those make-it-or-fail things? What is the SOP's purpose? In job hunting terms, the SOP is like a cover letter. The cover letter is to make clear connections between the resume and the job ad. For you, its primary purpose is to make the adcomm offer you admission with full funding. For the adcomm, its primary purpose is to help them see how you would fit into their program (make connections between their program and you). By fit, I mean do they have faculty (or enough faculty) in your area of research interest that can advise, mentor, supervise, and/or committee you through the program to get your degree? Do you have the kind of understanding of the discipline, your research interests, and their program that would make you successful? Do they have something to teach you? Offer you? What can you offer them? They want to brag on you as much as you want to brag about them. If they offer you admission, will you be a good scholar? A good student? Here is the most basic question the SOP should answer: What is it about you that makes you a better prospect than everyone else who's applying?
 
Understanding the SOP's purpose, in practical terms, means that you will know what to put into it and what to leave out of it. And how to phrase it.
 
So, with the purpose in mind, there comes the question: what should you put into it and leave out of it? What format should you use? (MLA? APA? Is footnoting okay?! What about citation?!) Should I stick in a personal story that everyone seems to recommend, except for the half that don't? My research interests? The story about why I got on F in that one, very important class? I'm not going to answer those questions because I can't. Every discipline and department is different. I will give you an answer you won't like: research. Find out the requirements each program you're interested in has for the SOP, think of the SOP's purpose: and now research.
 
Research is one of the basic keys to writing an SOP. It's no different than the writing sample you'll be including in your application packet. For each program you apply to, do some research. How much research you need to do depends on a lot of things, the least of which is your personality. More research does not automatically mean a better SOP. Less research doesn't automatically mean a better one, either. What makes the right amount of research? The ability to craft an SOP that is specific for the program that you're getting into. Here's some ideas (not an exhaustive, inclusive list of what to do) on what to research:
The program itself. Look at the recent graduates and, if possible, read their theses and/or dissertations, at least in part. The acknowledgements can give you an idea about the program's culture. The introduction can give you an idea about what kind of scholarship the program produces and expects. It will also, and this is very important, give you an idea as to how the program uses language. If you speak to them in their own language, that helps your case. You've likely done this, if not, seriously, you should have done this. Look at the program's website and read it all. What kind of classes are offered for both undergrad and grad. Who are the faculty, the tenured, the assistant, the visiting, the emeritus, and the graduate students. What kind of ties to the community (both academic and their local town) do they like to talk about? Do they talk about how their graduate students are working with community partners? Do they host conferences? What happened at the last one? This gives you a taste of the program's culture. The faculty. All of them that might be on the adcomm and the ones that are relevant or somewhat relevant to your interests. Crack open JSTOR etc. and search for recent faculty publications. If you're basing your interest on a faculty member on the interests they've got listed on the site and a reference to them in an article from a decade ago, or worse, only their reputation, you don't have a strong basis to establish clear reasons why they have anything to offer you. Read their recent publications, see who they name drop in terms of theory, other faculty, and so on. Make a list of what each faculty member can offer you in terms of research, not just the ones that are directly related to it. If you're into studying apples, but Dr. V works with oranges, think about how Dr. V's work might help you out. Take notes when you research. Each program has a bunch of people, and you're likely applying to multiple programs. It's easier to refer to notes than to go back and look it up all over again. What's happening in the field with your current research interests, if necessary. This is so you can situate your research interests in the discipline, and then situation your research interests in the program. You can just tell them what you're research interests are and leave the situating to them, but you can lose that chance to sell yourself as the best amongst the rest. Research you. Yup. You. Scribble out some lists or paragraphs or whatever that inventories you. Who are your influences? Who are the theorists you keep coming back to? Who are the theorists you loathe, mock, and/or ridicule? What are your research interests in general and specifically and anywhere in between? Some SOPs will need to be more general, some will need to be more specific. Length restrictions, what you found out about the program, the faculty, the state of the discipline, and so on, can alter this for you. What kind of scholar are you? Student? What's the difference? How do you manage your time? Stress? Health? Do you expect to bring your dog? Do you have health issues? Do you have any academic things that are a negative? If you do, how negative are they? It's easy to see that as an either it's entirely bad, or it's somewhere in the huge good category, but some things are negatives that need to be addressed for certain programs, while other negatives can be ignored, or you should discuss with the one relevant letter writer so they can address it. While Sam ultimately received a C in the Research Methods course, the grade doesn't reflect the actual scholarship as Sam fell ill during the mid-term and consequently failed it; my course policies do not permit re-taking the test. What are the good things about you? Not just the grades, awards, publications, and presentations, but also the character traits. What are you weaknesses? Don't do the job interview baloney, my greatest weakness is my perfectionism. Of course, the important, probably ought to be on the SOP questions: why grad school? What will you do with the degree you want? Why are into the research you're into? Why that particular school? Why are you worth admission and funding?
 
Research the assistanceships. Some SOPs will want you to write a bit about teaching or research with assistanceships in mind. So, do a bit of research on what these entail in the programs you're looking at. What do they do and how do they get it? Have you done assistanceships in the past? If so, what were they like? Do you have a teaching philosophy? If not, make one. Have you done anything that can be discussed in terms of the assistanceship? I taught kung-fu to white belt children, so I have teaching experience. I was part of the state herpetological society and went out to help them with their field counts twice a year. I learned that licking petrie dishes is always a bad idea, no matter how much they resemble pistachio ice cream.
 
Research SOPs. You're doing that, right? Go on to forums (like this one) and read the SOPs people have posted and then read the responses. Look particularly at SOPs in your discipline or related disciplines. Psychology might look at other social sciences. Physics might tell the joke about the Higgs Boson and Sunday mass. Bear in mind that the people responding to and/or criticizing the posted SOPs are likely not on an adcomm. Some have been  or will be, but it's not likely they'll be on the adcomm you're hoping will like you best. However, you can start to get a sense of what SOPs are like. What format is it in? Does yours look like everyone else's? Do you have the exact same opening sentence as half of the people hoping to get into a program in your discipline? I've always wanted to be a librarian since those wonderful, summer days I spent in my (relative of choice)'s home library. 
 
So, to take stock. First, understand the purpose. Second, research. A lot. Let the purpose of the SOP guide your research efforts.
 
Next, get the specific requirements for the SOP from each program. Make a list of similarities. If they all ask for a statement of your research interest, score! One sentence fits most! Most of them will be of different lengths and will have different ideas of what specific information they want. Most won't tell you enough, aside from length and one or two "should have" things. They mostly won't tell you if you should use APA or if you should footnote, or how to format it. Single space? Double space? They will tell you whether it should be on paper or what kind of file format to use. I have only one suggestion: consistency. Okay, two suggestions: unless otherwise specified, don't include anything other than the SOP. No bibliography or footnotes. If you quote or paraphrase someone, cite them in the text the way they do it in the average newspaper article. As Scooby says, "Ruh-roh!"
 
Now, start writing. Create something of a master SOP, or a set of master sentences for the SOPs. Some things should be in every one of them, like what your research interests are. Because length requirements are different for each program, you should work out more than one sentence or set of sentences for each thing you plan to put into more than one SOP. Have a more detailed explanation of your research interests and a more concise one. Even though this might be central and, perhaps, most important to the SOP, you don't want most of a short SOP taken up by one thing. Make these sentences do extra duties. If they can explain not only why you're into what you're into, but also why it's significant to the discipline/program, and how the program factors into it, bonus! The more functions one sentence can serve, with clear, readable logic, the more room you have in the length requirements to bring in other things. Think of this master SOP as more of a set of sentences you can hang on the individual SOP's unique structure. A flesh and skeleton metaphor can work here. You can order all SOPs at this point, you'll probably want to put research interests in the middle or toward the end, rather than in the first sentence, but the key here is that the skeleton of the individual SOP and most of its flesh will come from the needs of the program you're writing it for, not from some predetermined formula. No generically applicable, master SOP that has a few tweaks here and there.
 
Here's the thing. The SOP is one of the most important documents you'll write in your life. It's not something that should be done in a few hours, after looking at the program website and spending some time on the net searching for a how-to-write-an-SOP-guide. It takes work backed by research. The readers can tell quite easily how much research you've done on them by the way you structure and write your SOP. They can tell if you're sending out a generic SOP to several programs because it will be too general. You can't change faculty names in and out, along with a detail or two that makes it seem tailored to the program. The individual SOP should be tailored from the beginning. Some sentences won't change much, so you can pre-write them. But how they fit into each SOP, the reasoning you'll use to try to convince the adcomm that you're the best applicant, and the perspective you'll take all the way to the words you use should be done with the program in mind. It shouldn't be generic. Even if it doesn't seem noticeably generic to you, that doesn't mean that the adcomm won't notice it. They read many, many SOPs every year.

It's not in the explanation; it's in the usage.

Trust them to have enough education to make a few connections for themselves when it comes to the discipline. Example: Novels such as Twilight exemplify how Marxist alienation can be applied to childbirth.

So, be knowledgeable about you, your field, and the program, and use that knowledge well.

Crate training is a must for any dog that will live inside. People tend to think of it as cruel (doggie jail!), but dogs like dens. We covered the dog crate with a blanket, stuck a pillow in it, and pretty much couldn't keep the dogs out of it. The crate thing helps when you have to let repair-people in, or you're dealing with behavior issues or potty training issues, and a variety of things.

Make sure that you learn the laws of the town. Some people like to chain the dog up in the yard while they're away and a significant number of places call that illegal. No dogs on chains without supervision.

Make sure that you have the money to spend on quality food, various accessories (good leashes, etc.), licensing, and vet care. IMOM does great work providing grants for vet bills, but they've only got so much money. Dogs are expensive when they get sick.

Even if you get a dog that's been well trained, go through an obedience class with it. Obedience classes are more about training owners than training the dog. AKC runs several really good programs, like basic obedience and canine good citizen. A well trained dog is a joy. A dog that trains you, instead? Not so much.

Finally, you can't take muttly to conferences. Pre-plan pet sitting. You can check into doggy day care businesses, as well. Every semester I seem to have one day where I can't come home for about 14 hours. Dunno why, but it always works out that way. If I had a dog and no guy to be my doggy-daddy (that sounds weird), I'd take used a doggy day care for my long day. Or some other dog sitter. Large cities have dog walkers. The best business ever has been the yard cleaning industry. Once a week (or more often, depending on yard and dog needs) they clean the mess. Heaven! And not cheap.

I have snakes. I keep them in natural vivs, so I have to spend more of my energy taking care of their plants and soil than I do caring for them. I feed them two or three times a month (depending on season), and spend an aggravating couple of hours every month or so unwinding several feet of shed skin from plants, branches, and whatnot. But, I can leave the house for a few weeks without doing anything more than letting my non-phobic neighbor have a key and instructions on how to use the propane heater should the electricity fail for more than a day during the winter. I have a terrestrial, temperate species, so they spend most of their time snoozing in the dirt. And snake really are cuddly. They're just not the warm kind of cuddly.

First, my credentials. Well. I can spell my own name, though I don't usually know exactly how old I am. I'm within a year or two, but I'm usually wrong until I've done some subtraction. I teach composition and like to write calculus equations on the board when I take classes in poetry writing.

Even though this might be central and, perhaps, most important to the SOP, you don't want most of a short SOP taken up by one thing. Make these sentences do extra duties. If they can explain not only why you're into what you're into, but also why it's significant to the discipline/program, and how the program factors into it, bonus! The more functions one sentence can serve, with clear, readable logic, the more room you have in the length requirements to bring in other things. Think of this master SOP as more of a set of sentences you can hang on the individual SOP's unique structure. A flesh and skeleton metaphor can work here. You can order all SOPs at this point, you'll probably want to put research interests in the middle or toward the end, rather than in the first sentence, but the key here is that the skeleton of the individual SOP and most of its flesh will come from the needs of the program you're writing it for, not from some predetermined formula. No generically applicable, master SOP that has a few tweaks here and there.
 
Here's the thing. The SOP is one of the most important documents you'll write in your life. It's not something that should be done in a few hours, after looking at the program website and spending some time on the net searching for a how-to-write-an-SOP-guide. It takes work backed by research. The readers can tell quite easily how much research you've done on them by the way you structure and write your SOP. They can tell if you're sending out a generic SOP to several programs because it will be too general. You can't change faculty names in and out, along with a detail or two that makes it seem tailored to the program. The individual SOP should be tailored from the beginning. Some sentences won't change much, so you can pre-write them. But how they fit into each SOP, the reasoning you'll use to try to convince the adcomm that you're the best applicant, and the perspective you'll take all the way to the words you use should be done with the program in mind. It shouldn't be generic. Even if it doesn't seem noticeably generic to you, that doesn't mean that the adcomm won't notice it. They read many, many SOPs every year. People who read SOPs develop a sense about the generic, the cut and paste work.
 
How to name drop gracefully, or bring up the theory and histories and whatnot you're working with when there's only a teeny amount of space for everything? That's a bit easier than it might seem. It's not in the explanation; it's in the usage. If you can use the relevant theories and people and methodologies correctly in a sentence, you don't have to show the adcomm that you know how to use them, or how they're related, by explaining it. Trust them to have enough education to make a few connections for themselves when it comes to the discipline. Example: Novels such as Twilight exemplify how Marxist alienation can be applied to childbirth. My research interest lies in the alienation of women from the product of delivery in Modernist American fiction, such as Faulkner's Sound and the Fury. (Huh, I wonder if that would really work?) Two sentences and I've referenced theory, period, history, relevance for today, and some methodology (it's literature, not science). Use it, don't explain it.
 
If possible, have a professor you know read the SOP to your preferred school and give you some advice. They know more than most other groups of people. If not possible, your current university's writing center can help, or other people who are familiar with the field, or with writing. Your high school English teacher or your English major buddy can probably say something about your grammar, but might not be as helpful as expected. Example, in English, the convention is to speak of historical people in present tense. Shakespeare writes, "To be or not to be," because he thinks it is the question. History has kittens. Shakespeare has been dead for centuries, he can't write! Past tense! Shakespeare wrote, "To be or not to be," because thought it was the question. Someone in the field is preferable!
 
Finally, a word about my real credentials. The adcomm is going to do to your application what you've just done with this post. They are going to judge your credentials (your ethos, trustworthiness, veracity, credibility, knowledge, and so on) based on the impressions they get of you from what you've written. So, be knowledgeable about you, your field, and the program, and use that knowledge well.

First, my credentials. Well. I can spell my own name, though I don't usually know exactly how old I am. I'm within a year or two, but I'm usually wrong until I've done some subtraction. I teach composition and like to write calculus equations on the board when I take classes in poetry writing. But, here's my real credentials: consider what is written herein in conjunction with what the various instructions on SOPs that you've read have said, with the requirements the program you are applying to has put forth, and with your own experience as a writer. Do you think I know what I'm talking about? Should you pay any attention to it? Is any of it useful?
 
Second, I'm not going to give you a formula for what the standard SOP is like, or a list of things the various thousands of admissions committees will be looking for. There are plenty of prescriptions on the internet, many of them written by professors who have presumably gotten sick of badly written SOPs.
 
Third, I'm not promising that SOP writing be easier after this. It'll be harder, actually. I'm not promising that you'll get in to any place you desire, or that there is any one best thing to put in the SOP to get noticed. That would be totally impossible. Each discipline has its own needs and values, as does each university, each department, and each faculty member on the admissions committee (adcomm). There is no one size and it doesn't fit most, let alone all. There are conventions (use Standard English, for one), but other than include your research interests, I won't advocate that any one thing is strictly necessary. I leave that up to the more knowledgeable.
 
The advice:
 
First thing is to deeply understand that you should write an SOP for each program. Most people take this to mean write one master SOP and then tweak as necessary to make the one SOP applicable to each university (U of A becomes U of B, Professor X becomes Professor Y). You can do that. You can be very successful doing that. You most likely, really shouldn't do it.
 
The next thing to understand is the SOP's purpose. Why do the adcomms want to see SOPs? Shouldn't transcripts, letters of recommendation, and a writing sample do it? After all, transcripts and samples show the actual scholarship and the letters verify it. The SOP isn't for showing scholarship off, or to act like a resume, or anything. So why do the adcomms want an SOP? Why are the SOPs one of those make-it-or-fail things? What is the SOP's purpose? In job hunting terms, the SOP is like a cover letter. The cover letter is to make clear connections between the resume and the job ad. For you, its primary purpose is to make the adcomm offer you admission with full funding. For the adcomm, its primary purpose is to help them see how you would fit into their program (make connections between their program and you). By fit, I mean do they have faculty (or enough faculty) in your area of research interest that can advise, mentor, supervise, and/or committee you through the program to get your degree? Do you have the kind of understanding of the discipline, your research interests, and their program that would make you successful? Do they have something to teach you? Offer you? What can you offer them? They want to brag on you as much as you want to brag about them. If they offer you admission, will you be a good scholar? A good student? Here is the most basic question the SOP should answer: What is it about you that makes you a better prospect than everyone else who's applying?
 
Understanding the SOP's purpose, in practical terms, means that you will know what to put into it and what to leave out of it. And how to phrase it.
 
So, with the purpose in mind, there comes the question: what should you put into it and leave out of it? What format should you use? (MLA? APA? Is footnoting okay?! What about citation?!) Should I stick in a personal story that everyone seems to recommend, except for the half that don't? My research interests? The story about why I got on F in that one, very important class? I'm not going to answer those questions because I can't. Every discipline and department is different. I will give you an answer you won't like: research. Find out the requirements each program you're interested in has for the SOP, think of the SOP's purpose: and now research.
 
Research is one of the basic keys to writing an SOP. It's no different than the writing sample you'll be including in your application packet. For each program you apply to, do some research. How much research you need to do depends on a lot of things, the least of which is your personality. More research does not automatically mean a better SOP. Less research doesn't automatically mean a better one, either. What makes the right amount of research? The ability to craft an SOP that is specific for the program that you're getting into. Here's some ideas (not an exhaustive, inclusive list of what to do) on what to research:
The program itself. Look at the recent graduates and, if possible, read their theses and/or dissertations, at least in part. The acknowledgements can give you an idea about the program's culture. The introduction can give you an idea about what kind of scholarship the program produces and expects. It will also, and this is very important, give you an idea as to how the program uses language. If you speak to them in their own language, that helps your case. You've likely done this, if not, seriously, you should have done this. Look at the program's website and read it all. What kind of classes are offered for both undergrad and grad. Who are the faculty, the tenured, the assistant, the visiting, the emeritus, and the graduate students. What kind of ties to the community (both academic and their local town) do they like to talk about? Do they talk about how their graduate students are working with community partners? Do they host conferences? What happened at the last one? This gives you a taste of the program's culture. The faculty. All of them that might be on the adcomm and the ones that are relevant or somewhat relevant to your interests. Crack open JSTOR etc. and search for recent faculty publications. If you're basing your interest on a faculty member on the interests they've got listed on the site and a reference to them in an article from a decade ago, or worse, only their reputation, you don't have a strong basis to establish clear reasons why they have anything to offer you. Read their recent publications, see who they name drop in terms of theory, other faculty, and so on. Make a list of what each faculty member can offer you in terms of research, not just the ones that are directly related to it. If you're into studying apples, but Dr. V works with oranges, think about how Dr. V's work might help you out. Take notes when you research. Each program has a bunch of people, and you're likely applying to multiple programs. It's easier to refer to notes than to go back and look it up all over again. What's happening in the field with your current research interests, if necessary. This is so you can situate your research interests in the discipline, and then situation your research interests in the program. You can just tell them what you're research interests are and leave the situating to them, but you can lose that chance to sell yourself as the best amongst the rest. Research you. Yup. You. Scribble out some lists or paragraphs or whatever that inventories you. Who are your influences? Who are the theorists you keep coming back to? Who are the theorists you loathe, mock, and/or ridicule? What are your research interests in general and specifically and anywhere in between? Some SOPs will need to be more general, some will need to be more specific. Length restrictions, what you found out about the program, the faculty, the state of the discipline, and so on, can alter this for you. What kind of scholar are you? Student? What's the difference? How do you manage your time? Stress? Health? Do you expect to bring your dog? Do you have health issues? Do you have any academic things that are a negative? If you do, how negative are they? It's easy to see that as an either it's entirely bad, or it's somewhere in the huge good category, but some things are negatives that need to be addressed for certain programs, while other negatives can be ignored, or you should discuss with the one relevant letter writer so they can address it. While Sam ultimately received a C in the Research Methods course, the grade doesn't reflect the actual scholarship as Sam fell ill during the mid-term and consequently failed it; my course policies do not permit re-taking the test. What are the good things about you? Not just the grades, awards, publications, and presentations, but also the character traits. What are you weaknesses? Don't do the job interview baloney, my greatest weakness is my perfectionism. Of course, the important, probably ought to be on the SOP questions: why grad school? What will you do with the degree you want? Why are into the research you're into? Why that particular school? Why are you worth admission and funding?
 
Research the assistanceships. Some SOPs will want you to write a bit about teaching or research with assistanceships in mind. So, do a bit of research on what these entail in the programs you're looking at. What do they do and how do they get it? Have you done assistanceships in the past? If so, what were they like? Do you have a teaching philosophy? If not, make one. Have you done anything that can be discussed in terms of the assistanceship? I taught kung-fu to white belt children, so I have teaching experience. I was part of the state herpetological society and went out to help them with their field counts twice a year. I learned that licking petrie dishes is always a bad idea, no matter how much they resemble pistachio ice cream.
 
Research SOPs. You're doing that, right? Go on to forums (like this one) and read the SOPs people have posted and then read the responses. Look particularly at SOPs in your discipline or related disciplines. Psychology might look at other social sciences. Physics might tell the joke about the Higgs Boson and Sunday mass. Bear in mind that the people responding to and/or criticizing the posted SOPs are likely not on an adcomm. Some have been  or will be, but it's not likely they'll be on the adcomm you're hoping will like you best. However, you can start to get a sense of what SOPs are like. What format is it in? Does yours look like everyone else's? Do you have the exact same opening sentence as half of the people hoping to get into a program in your discipline? I've always wanted to be a librarian since those wonderful, summer days I spent in my (relative of choice)'s home library. 
 
So, to take stock. First, understand the purpose. Second, research. A lot. Let the purpose of the SOP guide your research efforts.
 
Next, get the specific requirements for the SOP from each program. Make a list of similarities. If they all ask for a statement of your research interest, score! One sentence fits most! Most of them will be of different lengths and will have different ideas of what specific information they want. Most won't tell you enough, aside from length and one or two "should have" things. They mostly won't tell you if you should use APA or if you should footnote, or how to format it. Single space? Double space? They will tell you whether it should be on paper or what kind of file format to use. I have only one suggestion: consistency. Okay, two suggestions: unless otherwise specified, don't include anything other than the SOP. No bibliography or footnotes. If you quote or paraphrase someone, cite them in the text the way they do it in the average newspaper article. As Scooby says, "Ruh-roh!"
 
Now, start writing. Create something of a master SOP, or a set of master sentences for the SOPs. Some things should be in every one of them, like what your research interests are. Because length requirements are different for each program, you should work out more than one sentence or set of sentences for each thing you plan to put into more than one SOP. Have a more detailed explanation of your research interests and a more concise one. Even though this might be central and, perhaps, most important to the SOP, you don't want most of a short SOP taken up by one thing. Make these sentences do extra duties. If they can explain not only why you're into what you're into, but also why it's significant to the discipline/program, and how the program factors into it, bonus! The more functions one sentence can serve, with clear, readable logic, the more room you have in the length requirements to bring in other things. Think of this master SOP as more of a set of sentences you can hang on the individual SOP's unique structure. A flesh and skeleton metaphor can work here. You can order all SOPs at this point, you'll probably want to put research interests in the middle or toward the end, rather than in the first sentence, but the key here is that the skeleton of the individual SOP and most of its flesh will come from the needs of the program you're writing it for, not from some predetermined formula. No generically applicable, master SOP that has a few tweaks here and there.

Crate training is a must for any dog that will live inside. People tend to think of it as cruel (doggie jail!), but dogs like dens. We covered the dog crate with a blanket, stuck a pillow in it, and pretty much couldn't keep the dogs out of it. The crate thing helps when you have to let repair-people in, or you're dealing with behavior issues or potty training issues, and a variety of things.

Make sure that you learn the laws of the town. Some people like to chain the dog up in the yard while they're away and a significant number of places call that illegal. No dogs on chains without supervision.

Make sure that you have the money to spend on quality food, various accessories (good leashes, etc.), licensing, and vet care. IMOM does great work providing grants for vet bills, but they've only got so much money. Dogs are expensive when they get sick.

Even if you get a dog that's been well trained, go through an obedience class with it. Obedience classes are more about training owners than training the dog. AKC runs several really good programs, like basic obedience and canine good citizen. A well trained dog is a joy. A dog that trains you, instead? Not so much.

Finally, you can't take muttly to conferences. Pre-plan pet sitting. You can check into doggy day care businesses, as well. Every semester I seem to have one day where I can't come home for about 14 hours. Dunno why, but it always works out that way. If I had a dog and no guy to be my doggy-daddy (that sounds weird), I'd take used a doggy day care for my long day. Or some other dog sitter. Large cities have dog walkers. The best business ever has been the yard cleaning industry. Once a week (or more often, depending on yard and dog needs) they clean the mess. Heaven! And not cheap.

I have snakes. I keep them in natural vivs, so I have to spend more of my energy taking care of their plants and soil than I do caring for them. I feed them two or three times a month (depending on season), and spend an aggravating couple of hours every month or so unwinding several feet of shed skin from plants, branches, and whatnot. But, I can leave the house for a few weeks without doing anything more than letting my non-phobic neighbor have a key and instructions on how to use the propane heater should the electricity fail for more than a day during the winter. I have a terrestrial, temperate species, so they spend most of their time snoozing in the dirt. And snake really are cuddly. They're just not the warm kind of cuddly.

Handling argumentative students over grading is actually very simple, for the most part. Instead of defending your grading, teach them how to advocate for themselves. The first step is to reassure yourself that you're human and you make mistakes and, more importantly, if you change a grade after careful consideration and acknowledging your error in a mature fashion that you can support with your course, you will get more respect from the students in general.

To teach them how to advocate for their grade (because profs do make mistakes, or they grade when grumpy, or something), don't answer their question(s), ask them a question. For example, why did Joe get 20 points on this and I only got 19? Stop and look at it thoughtfully for a period of time. In composition, I spend about 1 minute of time considering a paragraph, no less than 30 seconds considering a sentence. In other fields, an appropriate amount of time. This has two purposes. One, it gives them the impression that you are taking their concerns seriously and they appreciate that. Two, it allows you to stop and really think about why you did what you did and how that relates to the assessment criteria you applied--not why they got the points the got, but how their work relates to the grading rubric/assessment criteria. The next step is to shift their work so you can both examine it, but mostly so they have a stronger view of it. Then ask them what grade they should have gotten and why. If you have a copy of your assessment criteria that they can view, get it out. Lead them into making a persuasive case for their grade. If they have a different grade for the exact same work, obviously you've got to fix your mistake. However, most grading isn't like a set of basic addition problems in base ten, where it's either a mis-mark or it's not. A lot of grading is subjective because no two answers will be the same. Even multiple guess problems aren't pick the correct answer, but pick the best answer. Teach them how to present an argument with supporting evidence. It should never be a case of Joe got a 20 and I got a 19, my answer isn't that different, it's not fair, you should give me a 20, too. It should always be: I think I should have gotten this particular grade/this particular problem right because of X, Y, and X (all taken from lecture notes, the text, other credible sources, and/or your assessment criteria.)

Usually the first time you do this to them, they're completely unprepared. Smile. Tell the student that you'd like to give them the opportunity to prepare a bit with the text/lecture notes/whatever, so you'll see them in the next few days (name a day and time that would be convenient) to discuss the grade further. By giving them a specific appointment time, you focus their attention on when it would be good for them to come see you rather than on trying to argue fair instead of arguing the material.

The key here isn't that you stop them from arguing with you, it's that you stop them from arguing stupid. You can't defend against a student's conception of fair because they've already made up their mind what the fair grade should be based on, usually, personal feelings. Instead, you teach them to argue with you based on course material, which you can defend because it's not about feelings, it's about the course material.

I hand my rubric out at the beginning of the course, along with a four paragraph essay my then 14 year old kid wrote, and I teach them how I (and most people in composition) grade essays. I explain why I don't really care if they end sentences with a preposition, but their next professor might react any one of the more disgusting scenes from the Exorcist for the same offense. Then I tell them that if they believe the grade they get isn't what they earn, then they should come to my office hours with the rubric and their paper and make a case for the grade they should have. Of course, the first day of class, right after I pass out the syllabus, I sit on a table (if possible) and ask them how they know I'm qualified to teach the course.

There are some students that this does not work for. They argue because they don't believe you have the right to "give" them any grade other than what they think they "earned." Be firm, but pleasant (as possible). This is the grade this work earned; see chapter two in the textbook. If they don't drop it, refer them to your supervisor. ALWAYS maintain a log. Date, time, potential witnesses, and the gist of what of you said without editorializing.
