Harvard faculty vote to limit the share of top grades awarded to undergraduate students, aiming to curb long-running grade inflation. Multiple reports say faculty approve a mandatory cap on A grades equivalent to about 20% of students in an undergraduate course, using an “20 plus four” formula that allows additional A grades in larger classes. The policy is set to take effect in fall 2027. Reporting across outlets also says the vote passes with a clear majority, with around two-thirds to nearly 70% of faculty participating in support, though several describe the final tally slightly differently. A related reform approved by faculty would use average percentile rankings instead of GPA for certain internal awards and honors. Some plans discussed during deliberations did not pass, including a proposal that would have let individual instructors opt out of the A cap. Sources also note the faculty action follows concerns that a growing proportion of grades have become As—figures cited include increases over the past two decades. Student opposition is reported in multiple places, alongside criticism from faculty or supporters that the change could affect course access and signaling to employers and graduate schools.
