There are very few presidents without college degrees in American history. That’s not to say there haven’t been any, or that it’s impossible to work in politics without a college degree.
Legally, you can be elected president of the United States even if you didn’t go to college. The U.S. Constitution does not set forth any education requirements for presidents.
But it would be a pretty extraordinary achievement for a president without a college degree to be elected today.
But it wasn’t always common for presidents to have earned degrees or even attended college. In fact, educational attainment wasn’t a prime consideration among voters.
Education of Early Presidents
Fewer than half of the nation’s first 24 presidents held college degrees; they just didn’t need to.
“For much of the nation’s history a college education was a perquisite for the rich, well-connected or both; of the first 24 men who became president, 11 had not graduated from college at all (though three of those had attended some college without earning a degree),” wrote Drew DeSilver, a senior writer at the Pew Research Center.
The most recent president without a college degree was Harry S. Truman, who served until 1953. The 33rd president of the United States, Truman attended business college and law school but graduated from neither.
