Here Are the 15 Most Expensive High Schools in America

Getting the best education possible for their children is the goal of most parents in the U.S. However, for some families, this means sending their children to private schools, even starting with kindergarten. While private schools abound, it’s not something not every family can afford — especially if they have one of the nation’s most elite schools in mind — without financial aid.

According to the Education Data Initiative, the annual cost of private elementary school averages $11,207 per student and $15,645 for a high schooler in the United States. And, of course, the final bill depends on where you live.

In Connecticut, for example, the average tuition costs $22,564. That’s more than the $18,524 students will pay at University of Connecticut this fall. And on the low end, the average private school tuition in South Dakota costs $5,932.
