USMLE/COMLEX pass rates?

Howdy.

I was wondering if anyone knows where, for the various schools, I can find the board exam pass rates/percentages.

I have often heard that this is a good statistic to ask about at interviews. I have not, however, seen it published anywhere (such as on the USNews web pages or that sort of thing).

But it does seem like thing worth knowing. In any event attesting to the efficacy of the program in question.

Thanks!
