Why did Harvard cap A grades for undergrads?

Harvard votes to cap top grades, aiming to curb inflation

Harvard’s Faculty of Arts and Sciences voted to limit how many A grades undergraduates can receive, a move designed to make top marks “more meaningful” by reducing grade inflation. The decision comes from faculty members who approved a cap mechanism that restricts the number of students eligible for the highest grade band.

The change is intended to preserve the signal value of an “A” at a time when grading practices can drift over years toward awarding top performance more frequently. By placing a constraint on the number of A’s, the university is essentially increasing competition for the highest outcome and pushing instructors to grade more selectively.

In practical terms, the cap is expected to affect course-level grading distributions across the undergraduate curriculum, with potential knock-on effects for students’ GPAs, honors trajectories, and eligibility for certain academic distinctions. Harvard will also need to ensure departments and instructors can apply the policy consistently as they assign grades.

The policy also carries broader implications for the U.S. higher-education debate over how grading systems should be calibrated in competitive academic environments. As elite colleges consider reforms to preserve rigor and fairness, similar mechanisms—whether caps, standardized rubrics, or changes to evaluation systems—may become more visible nationwide.

For students and families, the immediate takeaway is that a straight-A outcome may become harder at Harvard, not necessarily because learning outcomes have changed, but because the grading system itself is being tightened.
