USA Today: “There’s a pretty clear trend: At four-year schools, awarding of A’s has been going up five to six percentage points per decade, and grade point averages at four-year colleges are also rising at the rate of 0.1 points per decade … And grade inflation is more prevalent at private institutions than at public ones … the mean GPA for both private and public schools in the 1930s was 2.3, or a C+. That number for both types of institutions increased at the same rate until recently – today, the average GPA at private colleges is 3.3 (a B+), while at public universities it’s 3.0 (a B).”
“Although the meaning behind an A still varies at different schools … receiving high marks could mean anything from ‘you showed up for class and didn’t insult the professor’ to ‘you’re a good to excellent student.’ According to a 2013 study conducted by the University of North Texas’s Department of Economics, class size may be one factor in the grade inflation increase, and departments with smaller student-faculty ratios have a greater tendency to exaggerate grades.
The type of degree program could also influence the extent to which professors overstate students’ grades: inflation was more prevalent among Ph.D. departments than it was among lower-level programs, according to the study.”
“Student evaluations could also incentivize instructors to issue higher grades than they deserve in an effort to ‘buy’ higher evaluation scores.”
