John F. Kennedy, the 35th president of the United States, once suggested that we "remember that our nation's first great leaders were also our first great scholars."

Case in point: Five of our first six U.S. presidents received a college degree, and the sixth, George Washington, received a surveyor's certificate from The College of William and Mary.

Lyndon B. Johnson earned his teaching certificate from Southwest Texas State Teachers College in 1930 (now Texas State University-San Marcos) and worked as a teacher before and after graduation.

Woodrow Wilson served as president of Princeton University and worked as a teacher prior to becoming President of the United States. John Adams taught before he went into politics, as did Andrew Jackson and Grover Cleveland (who landed an assistant teacher position through the help of his brother William).

Most of our presidents - 34 to be exact - have earned a bachelor's degree.

Jimmy Carter and Herbert Hoover studied engineering in college and earned bachelor's of science degrees. They are the only two presidents to have found work as engineers.

Ronald Reagan studied sociology and economics at Eureka College in Illinois, becoming an actor and sportscaster before launching his career in politics.

More than half of our 44 presidents (23 total) have been lawyers, including Obama, which is a trend that began with John Adams, our second president.
