The Effects of an Anti-grade-Inflation Policy at Wellesley College
Journal of Economic Perspectives, 28(3): 189-204 (2014)
Average grades in colleges and universities have risen markedly since the 1960s. Critics express concern that grade inflation erodes incentives for students to learn; gives students, employers, and graduate schools poor information on absolute and relative abilities; and reflects the quid pro quo of grades for better student evaluations of professors. This paper evaluates an anti-grade-inflation policy that capped most course averages at a B+. The cap was biding for high-grading departments (in the humanities and social sciences) and was not binding for low-grading departments (in economics and sciences), facilitating a difference-in-differences analysis. Professors complied with the policy by reducing compression at the top of the grade distribution. It had little effect on receipt of top honors, but affected receipt of magna cum laude. In departments affected by the cap, the policy expanded racial gaps in grades, reduced enrollments and majors, and lowered student ratings of professors.
Jim Schombert and I discovered similar disparities in our study of University of Oregon student grades. The inequities would be even larger after controlling for student ability. Eventually employers may demand learning outcomes testing (see Measuring college learning outcomes: psychometry 101), and the results won’t be pretty.
