There is almost no CEO, who hasn't got at least a bachelor degree.
Most also have MBAs or JDs.
There is this list, but it doesn't say who dropped out in the middle:

The only CEO of the top-50, whose education is listed as n/a is Martin
J Sullivan, the CEO of AIG, and despite my best efforts, I couldn't
find where (or whether) he went to college. However, if he hasn't gone
to college (which I doubt, I think that his full biography is just
unavailable online) he is the only one of those top-50. I have checked

Forbes also do not know anything about his education. I have emailed
AIG, and if they'll get back to me, I'll tell you for sure.

of Microsoft (he famousely dropped out of college). Steve Ballmer, the
CEO, has a college degree from Harvard.

their names on Google with the term "CEO" and "college OR
To summarise: 99 CEOs have a college degree, most of them have also
attended graduate school (in fact, those who haven't could be counted
on one hand). One CEO *might* not have a college degree, because none
is mentioned in any of his biographies. However, there is very little
biographical material on this specific CEO, so it is also possible
that he has graduated from college, but it is not mentioned on his
