UW is very competitive to get into. They accept 40 students a year into the program. They don't required an interview, so your admission is based on your application from PTCAS. I heard from a friend of mine that just graduated from the program. She said that application essays are really important.
I got accepted into the UW program, but decided to go to a different school because of cheaper tuition and cost of living. UW was my top choice school.
