Applying Yourself: Crafting the MFA Application, taught by Joe Fassler, who has read manuscripts for the Iowa Writers Workshop MFA, and has an impressive list of publications. This is an online course, so you could take it from just about anywhere.
Full Disclosure: I teach at Stanford, and it looks like Joe is also using the Creative Writing MFA Handbook as one of his texts. I don't know Joe, but this looks like a very helpful and relevant class. This is an FYI. 10 weeks, from July 1st to September 6th.
