School Rankings

US Boarding Schools —
Top 30 Rankings

Sort by endowment, tuition, acceptance rate, international percentage, or boarding percentage. Five metrics that reveal which schools have the resources, accessibility, selectivity, diversity, and residential commitment that matter most.

Why these five metrics

Endowment determines financial aid capacity, faculty quality, and institutional stability. Tuition is the headline cost — but with need-blind aid, the net cost can be radically different. Acceptance Rate reveals how selective each school is. International % reflects how globally diverse your peer group will be. Boarding % indicates how committed the school is to residential life.

Methodology & Sources

This ranking includes the top 30 US boarding schools by endowment, filtered to schools where boarding students make up at least 30% of enrollment. Primarily day schools with small boarding programs have been excluded.

Endowment figures are from FindingSchool.com's 2025–26 database, cross-referenced with BoardingSchoolReview.com. Tuition figures are approximate 2025–26 boarding tuition rates from each school's published fee schedule. Acceptance rates are estimated from published admissions data and Niche.com profiles. Need-blind financial aid status and average grant amounts are sourced from BoardingSchoolReview.com and individual school financial aid disclosures. International and boarding percentages are approximate. All figures may lag by one to two fiscal years.

Sorting by any column re-ranks all schools by that metric. Filters narrow the list without changing the sort order.
