The president of the United States may be the most powerful person on the planet, but the job requirements to get to the White House are surprisingly simple.
Of course, the commander-in-chief must be at least 35 years old and a natural-born citizen. But by some standards there are significantly fewer qualifications than other professions. There's no college requirement for example — just ask Harry S. Truman, who never earned a degree.
With no set educational or career path to follow, past presidents have been everything from police officer to professor, according to a recent report by CareerCast.
"A prestigious background still holds quite a bit of weight, but it doesn't necessarily determine your qualifications for the job," said Kyle Kensing, CareerCast's online content editor.
While certain pathways to the Oval Office are well worn, others are less so.
Military service is one time-tested route to 1600 Pennsylvania Ave., starting with the first president, George Washington, as well as Theodore Roosevelt and Dwight Eisenhower.
Many presidents are also former attorneys, including John Adams, Thomas Jefferson and Barack Obama. James Madison and James Monroe were among some presidents who transitioned into the White House from secretary of state.
Others held more uncommon professions prior to being elected. Click ahead for CareerCast's list of some of the more unusual ones.
