Actually, I have a list detailing which schools accept which types of transfers. Keep in mind, though, that schools may say "no" for this book the list is in, but if you have a really good reason - like engaged to one of their students - they may accept. I think it generally depends on how many spots they have open up that year. For instance, Iowa says "no transfers" on the list, but I've heard of someone who transferred from a DSM to Iowa (they were a resident and married to someone at Iowa I think). You should call the school you want to transfer to and ask - I've learned that is really the easiest way to get answers and they generally don't withhold info!
