Speaking to the faculty in my program, I've noticed that they seem to evaluate themselves and others using two criterion: (1) publication quality and quantity, and (2) ability to obtain grant money. No one discusses grades or performance in graduate school classes. Even when potential faculty candidates come around, this doesn't seem to be emphasized at all. What role do grades play in my PhD career?
Straight A's didn't get me into trouble with my advisor. My committee didn't care either.
I was always told there are three grades in grad school: excellent (A), adequate (B), and failing (C).
