Inside America's best high school - a boarding school that costs $53,900 a year and feeds students into the Ivy League

Phillips Academy, a prestigious boarding school located in Andover, Massachusetts, is the best high school in America.

It's founding dates back to the American Revolution - where its roster of early supporters reads like a "who's who" of American exceptionalism. George Washington, Paul Revere, and John Hancock all have ties to Andover, which the school is called for short.

That history, and the fact that the school originally educated students as a feeder school into Yale, likely contribute to the stereotype that Andover is a school for effete academics and wealthy families set on receiving a country-club style education, complete with uniforms, sports coats, and ties.

And yet, for all it's stereotypes of elitism, the Andover of today - formerly all male and all white - would be unrecognizable to the forefathers of America. More girls than boys that attend the school, 48% of the class are students of color, and the school's mission is driven by a charge to actively recruit even students who can't pay their full way.

So Business Insider toured the school's idyllic New England campus to see what makes Phillips Academy the best school in the nation.
