The ACGME has a one-time survey administered I believe every 3 years. It's a general survey, not geared towards pathology residencies. When I was at the CAP RF meeting last, I remember residents at the table talking about how their program somewhat-but-not-really tried to coach them re: how to answer it.
Once you attempt to get program-specific, there are all sorts of people you can piss off. And in the interests of jobs, fellowships and being generally seen as "nice and agreeable to work with", there are many residents who have a general fear of "repercussions".
Hence Scutwork.com, a relatively anonymous medium. Because it is apparently anonymous, it gives residents an opportunity to air their grievances. It's a good start. With the caveat that given a known population of residents in a program, it is often not hard to figure out who wrote a review, so it's not terrifically anonymous.
so somatic, what sorts of questions would you like to see on a residency graduation survey?
