I'm not a PCOM student, but since no one has replied, let me offer my $0.02 for you to consider.
The major medical schools in the state (U.Penn, Temple, Jefferson, MCP) all have strong affiliations with the major hospitals in the Philadelphia area as well as in Pennsylvania in general. These institutions tend to exclude students from non-affiliated schools.
PCOM students, as a result, have to rotate through the small community hospitals during their third year, and many of their rotations are really glorified office preceptorships. The loss of the PCOM hospital on campus hasn't helped the school either.
Again, these are the observations of an outsider. I'm a NYCOM MS-IV who spent 3 weeks at PCOM for an elective rotation. The impression I had after those three weeks of being on campus and speaking to the students was that PCOM had an excellent 1st and 2nd year education but a very poor 3rd and 4th year by comparison.
I'd suggest this: when asking PCOM students about their third year and 4th year rotation, specifically ask about the institutions they rotate through (whether these institutions have residents or not, and whether they are university-affiliated hospitals) and if they had any core rotations (other than Family Medicine) where they did a "preceptorship" instead of a hospital rotation.
