I think that MrMatt's point is just that. Last year they ranked their CHC's at the interview, then, if they were accepted, they were also told at which CHC they would be at, right at the time of the acceptance.
The way they are doing it this year, you just don't know where you're going to be for the next three years. I am kind of uneasy about this too, and really really wish that it were the way that it was last year.
To Bruce, Matt and others: I can tell you this much--during my first year there was a lot of switching between CHCs going on by many students which im sure was a headache for the school and the CHCs. A lot of the decision on which CHC people were assigned, predominantly was based on first come-first serve, meaning the earlier you were accepted the more likely you got your choice CHC. This situation truly was not fair, and i think excluded some people from more ideal CHCs. Thirdly, from the experience at my own CHC now, and from what I have heard about others, some students just are not the "right" fit for the CHC that they are now assigned too. The decision of which CHC these students chose was solely on the ranking the student gave the CHCs, and the order of their acceptance to the school. The CHCs had no choice in which students attend their campuses. Very commonly, the choice was a matter of student preference, no matter if they were not a good fit for the CHC--thus the "cooler" locations get chosen first NYC, HI, Seattle, Portland. The problem is that once relocated to the CHCs, the student and the CHC may not be a good match. This not only can be a disappointing situation for the student, this is a not a good situation for the CHCs, who are trying to find med students who are willing to stay at the CHCs in the future, and who fit well with not only the CHC, but more importantly with the population being served.
The way SOMA has changed the selection process, I think makes more sense. The CHCs will get a chance to also check out the students, and then after an interview process pick the people who are a good match for the CHC, and NOT get students who want to go to their CHC just because they want to "surf right after clinic for the next 3 years", or whatever other lame reasons I have heard from other students for choosing their CHC.
If you truly can justify why a specific CHC should spend time, money and effort for the next 3 years to train you to be one of their own "home grown" physicians, and also impress upon them why you make a good future doctor for their particular patient population then you will get the CHC that is the right fit for you, and the CHC will get the right student for them. Just make sure your reason is more valid than the earlier one I mentioned.
Oh and BTW, for many other med schools your clinical rotations are happening wherever you may get assigned for your rotations, which your not going to find out until your second year of med school, not to mention you may be moved around for rotations. At SOMA your going to know where your assigned for the next 3 years, probably by Thanksgiving. I think thats still a good deal.
P.S. I love my CHC, and feel lucky that I am at the CHC which is my ideal fit.
