There’s a thread on CC for the Sophie Davis program, which is a free program in NYC. They tend to give their stats, volunteer activities, and later report whether they were accepted. That thread will be skewed somewhat because Sophie Davis is a free program and they ask that in return the graduate work in specific areas. This may or may not influence who’s applying, but at least you can see some of the stats.
Also: I’ve been warned off of these types of programs by a mom whose daughter went before me. She said that they are very intense. Very intense. They’re great if you know that this is exactly what you want to do, but it’s no easy ride. There’s no real break from these studies.
These are prefect for many people, i’m sure, but you want to be sure they are perfect for you.
