Students in private schools consistently score above the national average, according to the Council for American Private Education.

It cost about $12,509 a year to educate public school student in 2013-14, according to the National Center for Education Statistics, while the average private high school tuition ranged from $9,790 (Catholic schools) to $25,180 (non-sectarian) in 2011-2012.

But the schools on this list start at over $40,000.

While grade schooling is provided by the government and paid for by taxes, parents of means do have the option of sending their children to elite private schools. These schools are very exclusive, often have famous alumni, and are all extremely expensive. All of the schools on this list have a higher tuition than the average four-year colleges and universities in this country. Fees are excluded from the tuition, except where noted.
