Since I am a first year I cannot comment fully on the third and fourth years but I will give you what I know. When I was selecting the medical school I was going to go to, I heard the same rumor that Yale isn't a great clinical training school. What I hear from the 3rd and 4th years here (when they do away rotations) is that they are confident at other places and are not lacking. They feel they are equivilant if not better than the 3rd and 4th years at other institutions. In addition, the match lists at Yale speak for themselves. Residency director's place a high mark on a Yale education and I would assume that has to include a high satisfaction with our clinical training. Of course I have a huge bias since I go here but I do believe that I will get a top of the line clinical education in the 3rd and 4th years (and actually even some now) compared to any of the other top schools. If this is something that you are truly concerned about you can always ask for 3rd and 4th year's emails at 2nd look, or talk to some of them who come and see what they say directly.
