Catherine Rampell checks in on grade inflation:
As we have written before, private colleges and universities are by far the biggest offenders on grade inflation, even when you compare private schools to equally selective public schools.
Thoreau's two cents:
My first thought is that this graph makes it pretty clear that the A and B and have been inflated. However, any study can have all sorts of flaws, so I need to delve more deeply into the study before I draw a firm conclusion.
