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.

Undergraduate studies are about, um, being taught with some independent-ish scholarship at the end. This varies by student and by discipline, but for the most part, there are few research projects included as a part of the program. Undergraduates must make their own research opportunities and move toward scholarship on their own. Sometimes faculty will encourage them, sometimes not. Graduate studies are about independent scholarship, not being taught. In the MA/MS program, there is that transition from being taught to independent scholarship, but the thesis is supposed to not only be representative of a student's best work, it should be proof that the student is capable of independent scholarship. The PhD program has little being taught involved. Yes, there are classes, but the student is expected to contribute as much to his or her own learning as the teacher. In a PhD program, you shouldn't expect much help from teachers, you should expect to be sort of colleagues-in-training. Colleagues don't tell you what to do, they help you figure out your options.
 
You keep returning to this characterization of yourself as a struggling student and the characterization of your adviser as an unhelpful person. I take your word for it that you struggled because you tried out scholarship that was beyond your capabilities and, reading between the lines, reasonably beyond the capabilities of the average MA student. I have a choice of ways to understand the phrase "struggling student"; its meaning depends on context. What were you struggling with? The material itself? The paradigm shift from undergraduate student to graduate student and all the new expectations and conventions that come with it? Yourself? Most of the time, "struggling student" is a student that has difficulties with the material. Sometimes, it's a student that hasn't adapted to the methods, expectations, and/or conventions of the learning situation. Sometimes, it's a student that has to struggle with his or her own self-doubts, lack of confidence, and so on; every student has these, but for some, they are an outsized impediment, rather than a more normal evaluation of ability. Sometimes, it's nothing more than maturity, a student struggles because he or she was not ready for the program. A lot of college freshmen drop out because they aren't ready for college. They need to do other things first. It's normal. Figure out what you struggled with the most. Currently, it sounds as if it was the material. As much as you love philosophy, if you struggle with the material, you might end up as one of those PhD candidates that never makes it past the coursework into comprehensives or the dissertation.
 
You believe in yourself and you have a goal. You are willing to evaluate criticism. This is most of the battle.
 
I suggest that you go to the university library and read theses written by graduated philosophy students. Read dissertations by philosophy students. The library should have these copies either in book form or electronically archived. Compare your scholarship to their scholarship. The dissertations will give you a strong idea as to what the philosophy department, and your adviser, considers to be appropriate scholarship from a PhD candidate, appropriate enough for them to certify that this person has earned a PhD. A dissertation is not just the student's best work, it's new knowledge added to the field. Can you do that?
 
The thing about this issue that bothers me is that your thesis committee signed your thesis when they thought it wasn't good enough. Why was your thesis good enough to get you an MA if your committee thinks it wasn't that great?

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.

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.
 
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 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.
 
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.

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!

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. Do you think I know what I'm talking about? Should you pay any attention to it? Is any of it useful?

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.

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. 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.

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. 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.

Never happened to me. I did know someone in an MA program that had this advice from an adviser. It went down like this: the adviser scheduled an appointment with my friend-quaintance after mid-terms and before advising, on a Friday afternoon, and during this meeting suggested that he might not be suited to the graduate program and had he considered what he could do with his current degree, or what he might do with a bachelor's in an information science field in addition to his current BA. According to him, the adviser was an evil biscuit who got off on harassing the men in the program because she was a rabid feminazi man-hater. After he fail!bombed the next semester, she helped him get into a BS program in another university. He makes apps now. And a lot more money than the feminazi does.

I bring this up because of the devil's advocate thing. Not everyone is suited to a graduate program, or the work people who actually graduate do, or the field they've chosen, or whatever.

Just because an adviser is mean, sadistic, and jerkish doesn't mean they're wrong any more than an adviser being supportive, compassionate, and helpful means they're right. I don't know if my sorta-buddy would have failed if he didn't have the adviser's "you can't do this" stuck in his head. I don't know if he would have succeeded. By bringing it up to him, we'll never know, really. There are tons of people who fail/quit grad school without faculty intervention. There are tons of people who wish they had quit, or that their adviser had spoken up years ago, before they'd invested that much time and money.

Considering my app-making pal's situation, I would likely advise the grad student to visit the campus counseling center to get their emotional equilibrium back, inasmuch as possible. Nothing can take your feet out from under you quite like an adviser or mentor turning on you. Once there's some emotional stability, I'd likely turn to a faculty member familiar with my work and solicit some criticism (what are my weaknesses? strengths?). Then I'd make a rational decision about my future based on evidence. Ah, who am I kidding. I'd laugh in my adviser's doubting face and likely critique their work. What can I say? I'm old and I over-value my own opinion.

Residency is a funny thing based on the laws of the two states involved. For people going to school, this generally means that you have a residence (leasing a room qualifies) for about 9 months per year in the school's state, and about 3 months in your state of origin. Each state has laws defining what residency means for 1) tax purposes and 2) voting.

Changing residency doesn't immediately mean getting a driver's license. It can mean nothing more than moving into a place that you intend to spend 75% of your time for the next 2 to 6 years.

The place to check about residency rules is generally the home state's and the school state's department of revenue (or where ever they locate their tax laws). One thing that most state have in common is the idea of intention. If you establish a residence with the intention of staying there permanently, you must change your residency (change driver's license, voter registration, vehicle tags, and so on).

If you must file taxes, and you don't change residency, you will have to file taxes in both states. You should get all taxes paid back from the school's state because you are not a resident. This means you may have to pay taxes to your home state.

As far as car insurance goes, they don't care what's on your driver's license. They charge based on the home address where the vehicle is most often parked. This means the place you live when you're at school.

Thank you for proving my point.
 
As you would not be happy in an English department, which finds hasty generalizations and the concept of "words on a page" as unpalatable as you seem to find literary approaches to Shakespeare. Less so, perhaps, since hasty generalizations are a sign of poor abilities with rhetoric. Thus, we are all very pleased that you are not in English. Though, I have done fine in theater.

But am I a rarified beast? I'm starting on my PhD at the same time my son is starting on his BA. Most of the people in my MA cohort weren't born when I got my high school diploma. I remember research before the Internet, though I have no idea how I lived in a world without google. No, really. I can live happily without a microwave, without cellular service, without bar code scanners, without DVDs and CDs, but no search engines or wifi really sucked in retrospect.
 
Sometimes, I feel like I'm going to be that old lady at my MA graduation ceremony, the one who got a standing ovation and a write up in the paper because she got her degree as an old lady. Of course, she was not only 88, but a really nice woman. I'm 41 and, well, nice is usually used ironically. I hope I'll be done way before I turn 88. It seems like I've been at this education thing forever. I like being older. I don't get the kind of guff from students that most of my cohort did. I don't know if that was age or just me. I have some insight into Raymond Carver because I remember the 70s. Too bad I'm not fond of Carver. I also saw Star Wars, opening night, in the theater. I was 8, but what the heck, right? Billy Idol videos make perfect sense because I grew up under the threat of global thermonuclear destruction. Degree-seeking at this age is fun.
 
Anyone else starting out later in life? Do you think we'll have problems keeping up at recess?

I approached like any other essay. I started with a research question. Sometimes, the school provided a start, most of the tie, it didn't. I ended up with 4 specific questions that all of my SOPs answered, and in this order: 1) Why is a PhD for me? 2) What do I plan to accomplish during my time as a PhD student and after I obtain the PhD? 3) How can the department and its faculty help me obtain my goals? 4) Why is a teaching assistanceship a requirement for me? (The last question added depending on the school's stated requirements).
 
The first one was my "catch". It's the personal story that tells them about me, as a person, and why I'm not taking the PhD thing lightly. It was my "this is why you should like me better than anyone else" sentence. I wrote about 5 pages answering this question and managed to condense it into two and three sentences. I would interchange these sentences depending on the length of the SOP. The second question, I answered in about 3 pages, and condensed it into two sentences. I wrote several pages answering question 3 for each school. That took a lot of research (I read department blogs, faculty blogs, abstracts of recent dissertations and theses by current and former students, articles put out by relevant faculty and might-be-relevant faculty, even faculty dissertations (at least in part), checked which conferences they've been to, checked their social media, if available, to see what their interests were, in short: faculty stalker!).
 
I found the SOP how-to guides less than helpful. There was too much conflicting advice and none it was from the departments I was interested in. I took the common ideas (such as: give them something right of the bat to distinguish you from everyone else, and apply a nickname to, like sociology girl or library girl or whatever, because nicknames are easy to remember). The SOP is a cover letter for a resume. It's deeply personal. It's about fit.

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.
 
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.

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. 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!

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.
