Stanford Graduate School of Business has historically posted the highest class average GMAT scores for any prestige MBA program in the world. Wharton matched Stanford's score in 2018 after being behind the GSB by as many as 11 points in 2012. Wharton's average jumped 11 points last year but Stanford's new record prevented the school from tying or exceeding the GSB's score; this year Wharton was flat while Stanford slipped 1 point.
