This study attempts to isolate instructor-specific measures that may be sources of grade inflation and to measure their relative importance.
We estimate a fixed-effects model, using by far the most extensive data set related to grade inflation ever assembled. Our data comprise 48,038 courses taught by 1,871 distinct instructors at a large public university over a two-decade period.
Our results suggest that female faculty members are the most likely to inflate grades, while ethnicity has a lesser effect.
Characteristics of instructors, in particular gender, affect the degree of observed grade inflation, controlling for student- and department-specific effects.
