FWIW, I think I've said all this before: At one place I was at, residents didn't always even know a frozen had happened, much less grossed it for frozen, cut/stained the frozen, or looked at it. Residents generally had to go out of the way to collect them at the end of the day and look at them, if they were missed in real time. With enough effort, paying attention, and browbeating the attendings, one could get more involved. That place was organized as private, contracted to take residents.
At the second place, residents answered the frozen section pager and called the attending when it was time. Residents grossed for frozen, cut/stained the frozen, and were expected to look at it with the attending (if not before, if they were running late) in real time unless there was a high volume, then called in the result. If there was a high volume at that moment, residents still reviewed them with the attending as soon as possible before the attending left the room. That place was a more typical academic department. The only variation was sometimes with neuropathology; one of the neuropaths would be called first and the surgpath resident occasionally left out, unless you were on a neuropath rotation, which I -think- everyone had to do. Senior residents were expected to do all the talking/interpretation, unless or until you ran into a brick wall or were going down the wrong path, at which point the attending would pipe in and right the ship.
Basically, although good books always help, there's no substitute for being the on-the-spot dude/dudette looking at a frozen and trying to figure things out while the surgeon is drooling in anticipation, a junior resident is mumbling incoherent possible diagnoses, and your attending is giving you some look between supportive encouragement and "why hasn't he said what it is yet? It's so OBVIOUS!"
