To add a current student's perspective on grade disclosure...
IT'S NOT A BIG DEAL. Seriously, grades do not really matter. You do NOT have to put it on your resume - in fact,
most do not. The only companies that ask are McKinsey and finance recruiters. And the best part is that Sloan is not competitive at all, even with grade disclosure. We all "care" about our grades (we wouldn't have gotten here
without caring, right??) but then you realize that it's not going to make any difference in recruiting. You work hard and do well for personal satisfaction and for your team since many assignments are team-based. Second year students reinforced this to us all semester...or perhaps they were just trying to find more drinking buddies
On the flip side, what can happen with grade non-disclosure is this:
"“Grades don’t matter (Michigan has a non disclosure policy for grades, as do most schools) and they should so students have more of an incentive to come to and participate in class.”"
