During the last school year, about two-thirds of all undergraduate letter grades were A’s. Under the new proposal, grades of A would be limited to 20 percent of grades in a course, with an allowance of four additional A’s.
So, for example, a professor teaching a class of 100 students would be able to award up to 24 grades of A under the proposal, which could come to a vote by faculty this spring. There would be no limits on A-minus and lower grades.
