With playwriting MFA’s, it really all depends on what kind of program you’re looking for. Sarah Lawrence (which is where I went for Undergrad) offers an MFA in playwriting, and their philosophy is very do-it-yourself, which means that you essentially build your own curriculum and are working very closely in small classes with faculty as well as building theater projects with other students, both Graduates and Undergraduates alike. I’m presently at Columbia for my MFA and they’re a little more structured, though I by no means feel as though they’re forcing me to work on anything I would not have otherwise wanted to work on. Other programs that I’ve looked into are as follows: Yale, Brown, NYU, The New School, Brooklyn College and Iowa.
And I also think it’s important to consider what you want your MFA for, because almost all playwrights do not make their living by writing plays alone -- there just isn't money in it. So, do you want it to focus in on your own craft? Is it to learn other forms of Dramatic Writing (read: screenplays and teleplays)? Is it so that you can teach? Or is it so that you can have a career in theater while being a playwright (read: lit manager or other kind of production company member)?
If you want to work in the theater, I think it’s incredibly important that you get your MFA in New York, so that you have an opportunity to have jobs and internships in the NY theater world. I also think that if you’re going to study playwriting, you should see as much theater as possible, and that’s just easier to do in NYC. Though it isn’t far from Bronxville (where SLC is) to the city, and there is a lot of good theater at the Yale School of Drama.
I would caution you against two things: Brooklyn College has an interesting-looking playwriting program that is a part of their creative writing program and not their theater program, but in my dealings with them, they were disorganized, slow to respond and ultimately offered me acceptance into their Masters of English program, not their playwriting MFA program. Additionally, the application for the New School is horrendous, more like reality TV than application to an MFA program. Though I continue to hear excellent things about the program itself.
I hope this helps! If you have any further questions, please don’t hesitate to ask me. I’d love to help if I can.
In fact, I may post this on the MFA blog so that other people can throw in their two cents as well.
