Students at Cornell University's Samuel Curtis Johnson Graduate School of Management voted for grade nondisclosure, effectively immediately, after years of agitating for a policy similar to those in place at other highly selective M.B.A. programs. Under the new policy, one-, two-year, and Johnson Cornell Tech M.B.A. students can't disclose their grades to recruiters until they've been offered a full-time job. That means grade-point averages, but also individual course, assignment and exam grades. Exceptions include dual degree students, such as those enrolled in a joint law program, and those applying for jobs abroad or in nonprofits or government. Fellowship applicants also may disclose their grades.
