Earlier, I posted two items on grades at Witt. One dealt with how hard (at a point in time) particular departments grade compared to each other. Another dealt with how grades at Witt compare to grades at other schools, also at a point in time. It included the phrase “grade inflation” in the title, a really bad mistake for an economist! Why? Inflation deals with change over time.
Doug Andrews posted a comment with a question about grade inflation. He provided the pre 2000 data he had gathered in his capacity as a Phi Beta Kappa adviser. It represents cumulative mean GPA for grads at the point of graduation. I have assembled data for the post 2002 mean cumulative GPA for grads.

It seems clear to me that grades have crept up over time.
