America's Top CEOs and Their College Degrees

Who says you need a college degree to be one of America’s top chief executive officers (CEOs)? Well, the law of averages does. You may say there are a few exceptions, including Bill Gates and Mark Zuckerberg. We will say we agree, but there is a nuance. Both Gates and Zuckerberg came to become CEOs from a startup founder and entrepreneur path and not from a corporate hiring and grooming path.

Having a formal education is a standard requirement for the top tier of the business world. The path to becoming a Fortune 500 CEO can include more than a college degree, but make no mistake—it often includes a stop at one (or two) of the country’s colleges or universities.

While a bachelor's and a graduate degree are common for top CEOs, there is no single major or graduate degree that they all share. Although business and computer science degrees are solidly represented, there are some less common inclusions. And of course, the majority of the CEOs obtained a Master of Business Administration (MBA). Keep reading to discover the undergraduate and graduate degrees of some of the country’s top CEOs.

Key Takeaways
