This Ivy League School Has Produced the Most Powerful Businesswomen

Of the 51 women on the 2016 list, nearly 20% graduated from Harvard University—three as undergrads and seven as graduate students. Two, Facebook CEO Sheryl Sandberg and CVS/Pharmacy president Helena Foulkes, actually attended the Ivy for both degrees.

That being said, only seven went to an Ivy League school as an undergraduate. Among those who earned their undergraduate degrees in the U.S. (six earned their diplomas abroad), 27 went to a private university and 15 attended a public one.

One of our honorees, Crystal Hanlon, president of the Northern Division for Home Depot (No. 41), made it to the list despite never completing her degree at the University of Houston.

The majority of the Most Powerful Women are no strangers to the classroom—well over half received a graduate degree of some sort, and one, Mondelez CEO Irene Rosenfeld, even boasts a doctorate.

(The data includes 47 of the 51 women on the list. Ross CEO Barbara Rentler did not release her educational history; Crystal Hanlon did not complete her degree; and our fun No. 51, Beyoncé, did not attend college)

MBAs are by far the most popular secondary-degree among the Most Powerful Women—65% hold one. Others boast graduate degrees in topics like engineering and economics, and three women graduated with a JD.
