AAMC.
Re: Holy Cross, as @CottonTales notes, it is a good idea to see how a college uses its Health Advisory Committee (different names at different colleges). HC doesn’t seem to prohibit students from applying to med school, but it does provide candidates with an assessment of the probable “tone and content” of their committee letter, and I’d guess being told they’d receive a low recommendation would discourage some from applying. Not necessarily a bad thing, but something to be aware of at any college. As far as what HC claims regarding their med school acceptance rate, I have not seen 10 years worth of AAMC stats, but from what I have seen they must have a lot of DO acceptances (their recent MD rates are definitely above average, but not close to 80%). But again, (repeat after us) it’s the student, not the college that gets them into med school.
