I sent an email to my professors asking when they were available to discuss a potential recommendation letter. If I haven’t had that professor in a while, I will remind them who I am and what class I had with them as well as what grade I got. After we set up a time to meet at their office, I brought my resume, transcripts, personal statement, and a list of schools with deadlines in a manila envelope to give them.
Some schools offer leveling Masters programs which allow you to take prerequisites the first year and then matriculate into the grad program. You won’t be able to apply to programs that don’t have that because they want you to have had a postbac done for SLP or have your bachelors in communicative disorders.
