Out of state or out of region? If you're in the WWAMI (Washington, Wyoming, Alaska, Montana and Idaho) region go for it! If you're outside of that region the odds are not in your favor.
From the UWSOM FAQ (
Admissions Frequently Asked Questions | UW Medicine):
"
Applicants from outside the WWAMI region who come from either economically or educationally disadvantaged backgrounds and/or who have demonstrated a significant commitment to serving underserved populations will be considered."
"
Out of region applicants must have an exceptional record of service or come from a disadvantaged background to be considered."
From the UWSOM Acceptance Statistics (
Acceptance Statistics | UW Medicine):
For the entering class of 2017, 288 people were accepted out of 1356 applications from the WWAMI region, an acceptance rate of around twenty per cent (crazy high compared to most medical schools). In contrast, only 44 students were accepted from 7251 out-of-region applicants, an acceptance rate of roughly 0.6% (in comparison, Harvard's
matriculation rate is around 2%)
TL;DR - On a purely statistical basis, if you're out of the WWAMI region UW is one of the hardest schools in the country to get in to.
Wow sorry for the wall of text lol. Guess I got a bit carried away.
