Harvard, Stanford MBAs Top Graduate School Rankings

Harvard and Stanford business schools shared the top spot in this year's rankings of graduate schools released Tuesday by U.S. News and World Report.

The ranking was based on GMAT scores and undergraduate grade point average of entering students, and salary after graduation.

The Wharton School at the University of Pennsylvania came third, and Massachusetts Institute of Technology's Sloan School of Management, Northwestern University's Kellogg School of Management, and University of Chicago's Booth School of Business were tied for fourth.
