Last spring while I was finishing my fellowship at Columbia Business School, much of the student body was busy trying to overturn the school’s grade disclosure policy. Back then, Columbia was one of the few top MBA programs that did not practice grade non-disclosure, meaning recruiters were allowed to ask Columbia students about their grades. By the end of the year, the issue had passed a student referendum, and this semester Columbia became the latest business school to have a grade non-disclosure policy, which encourages students not to disclose their grades to employers until they’ve been hired.
Grade non-disclosure policies are a quirk of MBA programs. You won’t find them in medical or law school. In fact, the only place you do find them is among top business schools. Of the 15 most selective MBA programs, 9 of them have some form of a grade non-disclosure policy. But of the schools ranked from 20 to 50, none do.
A new paper from a pair of Wharton economists examines why this is.
