Top 10 Colleges of Fortune 500 CEOs

What sort of education does it take to climb to the top of America’s largest companies?

If there’s one thing that can be gleaned from the educational backgrounds of the chief executives of the recently released Fortune 500, it’s that there are many paths to success. Many of them studied business, economics, or engineering, but others majored in art history, geology, psychology, and history. Sure, there are plenty of MBAs—173, to be exact—but there are at least 121 executives who didn’t go to graduate school at all, including major-company CEOs such as Rex W. Tillerson of Exxon Mobil, Stephen J. Hemsley of UnitedHealth Group, and Jeff Bezos of Amazon. Overall, the Fortune 500 crew attended 220 different colleges for their undergraduate degrees.
