Grade inflation is greatest at the elite universities such as Stanford. When I was at the University of Nevada, there were regional Department Chair meetings where I became acquainted with the chair of the Stanford Biology department back in the late '90s. He told me that he and most of his colleagues had given up trying to fight grade inflation since the students believed that they were all exceptional for having gotten into Stanford. The students felt that an average grade of C was unacceptable. So they only gave As and Bs.
Schools with the Highest Average GPA
I couldn't find data on the mean GPA at UConn. But it's a pretty significant achievement if student athletes have a similar GPA and honors placement as the general student population. Athletes have to work much harder than the average student in order to get good grades.
