The 16 most selective boarding schools in America

Attending a top-notch boarding school sets students up for lifelong success, but some of the most elite boarding schools are incredibly selective about which students are right for the experience.

Business Insider recently published a list of the most elite boarding schools in America. The ranking was based on three metrics weighted equally: endowment, acceptance rate, and average SAT score. Here we've re-ranked the schools based solely on acceptance rate to determine which boarding schools are the country's most selective.

Despite Phillips Exeter Academy's title as the No. 1 most elite boarding school for the second year in a row, it comes in at No. 8 on this list with a 19% acceptance rate, tied with Milton Academy. The Groton School, the No. 5 most elite boarding school, is tied with The Thacher School as the most selective, each with an acceptance rate of 12%.
