Before You Start: Essential Boarding School Context

  • Exeter and Andover are need-blind for domestic students — if admitted, your family pays $0 if income is below ~$75,000. The sticker price should not deter application from lower-income families.
  • The Eight Schools Association (Exeter, Andover, Choate, Deerfield, Hotchkiss, Lawrenceville, St. Paul's, Taft) is the traditional 'Ivy League of boarding schools' — these 8 schools have the strongest academic reputations and alumni networks.
  • Most top boarding schools are test-optional as of 2024–25. The interview and personal essays have become proportionally more important in the absence of required SSAT scores.
  • A boarding school education costs $63,000–$68,000/year at most top schools — but this is all-inclusive (room, board, activities, most travel). The all-in cost of a 4-year boarding education approaches that of elite universities.
  • Boarding school applications are due January 10–15 for September enrollment. The timeline is similar to college applications but occurs in 8th grade for 9th grade entry.

In-Depth School Profiles: Top 4 US Boarding Schools

#3

St. Paul's School

Concord, NH

Boarding-Only · Founded 1856
Type
Boarding only (no day students)
Campus
2,000 acres, Contoocook River
Student-Faculty
5:1
Notable Alumni
John Kerry, Robert Mueller

St. Paul's School in Concord, New Hampshire is the purest expression of the traditional American boarding school: it is exclusively boarding (no day students), enrolls only approximately 530 students in grades 9–12, and maintains a student-faculty ratio of 5:1. The school's 2,000-acre campus on the Contoocook River includes a working farm, an ice hockey rink, extensive athletic fields, and a chapel that anchors a traditional Episcopal Christian community life. St. Paul's curriculum integrates academic rigor with character development in the Episcopal tradition. The school offers AP courses and a robust arts program. Notable alumni include John Kerry, Robert Mueller, and numerous prominent figures in finance, law, and government. St. Paul's endowment funds significant financial aid; approximately 35% of students receive aid with an average grant of approximately $45,000/year.

#7

Groton School

Groton, MA

Smallest of the Top Eight
Enrollment
~390 students
Founded
1884
Notable Alumni
Franklin D. Roosevelt
Character
Episcopal, community service emphasis

Groton School is the smallest school among the Eight Schools Association with approximately 390 students — a scale that creates a particularly intimate community. Founded in 1884 by Episcopal minister Endicott Peabody, Groton historically served as the training ground for America's WASP establishment: Franklin Roosevelt (Class of 1900), Dean Acheson, and multiple Morgans, Peabodys, and Bundys attended. Today Groton is substantially more diverse and has actively recruited students from underrepresented backgrounds. The school's small size means every student is known by faculty; the student-faculty ratio of 5:1 is effectively even better in practice than the number suggests. Groton offers AP coursework and maintains a residential culture emphasizing community service and character formation alongside academic rigor.

#9

The Lawrenceville School

Lawrenceville, NJ

House System · Near Princeton
System
House system (British model)
Founded
1810
Location
Near Princeton University
AP Courses
22+

The Lawrenceville School, founded in 1810 near Princeton, New Jersey, is the most architecturally and organizationally distinctive school on this list. Lawrenceville uses a house system modeled on British public schools (Eton, Rugby) in which students live in residential houses of approximately 20 students each, with a faculty family in residence. The house is the social and residential unit; students eat dinner with their house, study in house common rooms, and develop mentoring relationships with house faculty. Academic life is shared across the broader school. Lawrenceville offers 22+ AP courses and places strong students at selective universities. Its location adjacent to Princeton University has historically led to college counseling relationships and campus access for advanced students.

#14

The Thacher School

Ojai, CA

Western Boarding School
Freshman Tradition
Every student cares for a horse
Location
Ojai Valley, California
Enrollment
~270 students
Founded
1889

The Thacher School in Ojai, California is the most distinctively American boarding school on this list: every freshman student cares for their own horse for the first year, a tradition dating to the school's founding in 1889. This outdoor education and horsemanship tradition is not merely decorative — it builds responsibility, physical capability, and connection to the natural world in ways academic programs alone cannot. Thacher is the leading boarding school on the West Coast outside of California's day schools. With only approximately 270 students, Thacher maintains a 5:1 student-faculty ratio and an intimate community deeply connected to the surrounding Ojai Valley's natural environment. The school offers AP courses and strong college placement. Approximately 30–35% of students receive financial aid.

Boarding School Admissions: A Step-by-Step Guide

1. Research (Spring/Summer, 8th grade year)

Identify 6–8 schools that match your student's academic profile, interests, and geographic preferences. Read each school's curriculum overview. Discuss family financial aid needs with each school's admissions office early — most are candid about typical aid levels for your income bracket.

2. Campus Visits (Fall, 8th grade year)

Schedule campus visits ideally in September–November. Visits typically include a campus tour, class observation, and a student/parent interview with an admissions officer. The visit is evaluated as part of the application — demonstrated interest and interview performance matter. Bring thoughtful questions about specific academic programs.

3. Application Submission (December–January)

Most top boarding school application deadlines are January 10–15. Applications include academic transcripts, teacher recommendations, a personal essay, and the Student Applicant Profile. Test scores (SSAT or SAT/ACT) are optional at most schools. Financial aid applications are typically due simultaneously — apply even if uncertain about eligibility.

4. Notifications (March 10)

Boarding school notifications arrive on March 10 by long-standing convention — sometimes called 'March 10 Notification Day.' Students have until April 10 to respond. This date is observed by virtually all Eight Schools Association members and most other top boarding schools.

5. Decision Considerations

If admitted to multiple schools, visit again if possible. Talk to current students directly about daily life, workload, and peer culture. Verify that financial aid awards are sustainable for all four years, not just freshman year. The school you choose should feel like a genuine fit, not just the most prestigious option offered.

Boarding School Financial Aid: What You Need to Know

Need-Blind Admission

Only Exeter and Andover (domestic applicants) are need-blind. They meet 100% of demonstrated need. Family income under $75,000 → typically $0 cost. Income $75–150K → graduated contribution. Income $200K+ → typically full tuition.

Need-Aware Majority

Choate, Deerfield, Hotchkiss, Groton, Lawrenceville, St. Paul's, Taft, and most others are need-aware — finances may affect some borderline admission decisions. But all provide generous aid to admitted students who need it; average grants of $40K–$56K/year are standard.

SSS Application

The School and Student Services (SSS) application (solutionsbysss.com) is used by most NAIS-member boarding schools. It's similar in scope to the CSS Profile for college financial aid. Gather your prior year tax return, W-2s, and asset information before starting.

International Students

International students face significantly less financial aid availability at most boarding schools. Exceptions exist (some schools have large international aid budgets) but families should inquire directly. Exeter and Andover are need-aware for international students.

The Eight Schools Association: The Historical Prestige Cohort

The Eight Schools Association comprises the eight boarding schools with the longest histories of academic excellence and institutional prominence in American education:

Phillips Exeter Academy

NH · Founded 1781

Phillips Academy Andover

MA · Founded 1778

Choate Rosemary Hall

CT · Founded 1890

Deerfield Academy

MA · Founded 1797

Hotchkiss School

CT · Founded 1891

The Lawrenceville School

NJ · Founded 1810

St. Paul's School

NH · Founded 1856

The Taft School

CT · Founded 1890

All eight schools are recognized by selective college admissions offices as providing rigorous preparation for demanding undergraduate programs. A student admitted to any of these schools and who performs strongly (GPA, intellectual engagement, extracurricular depth) is exceptionally well-positioned for selective college admission.

Frequently Asked Questions

What grade do students typically enter boarding school?

The most common boarding school entry points are 9th grade (Form III or Freshman year, the most common entry point) and 10th grade (Form IV, available at many schools including Exeter and Andover). Some schools like Choate also admit into 11th grade (post year or 'PG' — postgraduate year for students who want an additional year before college). Most top boarding schools do not admit students after 9th grade as a standard path, though mid-year and 10th grade entries are possible at some schools. The admissions process takes place in January–March preceding September enrollment. Students applying to 9th grade submit applications in December–January of their 8th grade year.

What is the application process for top US boarding schools?

The top boarding school application process typically includes: (1) The Student Applicant Profile — an extended personal essay or responses to school-specific prompts; (2) Teacher recommendations — typically 2–3 from English and math teachers plus a counselor recommendation; (3) Academic transcripts — usually 6th–8th grade records; (4) Standardized test scores — SSAT (Secondary School Admission Test) is the standard for boarding schools, though most are test-optional as of 2024–25; (5) Campus visit and student interview — virtually all boarding schools strongly recommend a campus visit with student interview. Most top schools accept SAT or ACT in lieu of SSAT. Applications typically open in September and have regular decision deadlines in January 10–15. Financial aid applications are typically due around the same time.

Is the SSAT required for boarding school admission?

As of 2024–25, most top boarding schools — including Exeter, Andover, Choate, Deerfield, Hotchkiss, and Groton — have adopted test-optional policies. This means the SSAT (or SAT/ACT) is not required for admission. If submitted, scores are considered alongside other application components. Students who feel their SSAT scores accurately represent their academic abilities should submit them; students who feel the test score underrepresents their abilities may choose not to submit. The SSAT is available at testing centers nationwide and through home administration. Prep resources are available free from the SSAT organization (ssat.org) and through purchased courses. Given the test-optional shift, the interview and essay components of boarding school applications have become proportionally more important.

How does the Five School Association relate to school choice?

The 'Eight Schools Association' (sometimes called 'Ivy League of boarding schools') comprises Exeter, Andover, Deerfield, Choate, Hotchkiss, Lawrenceville, St. Paul's, and Taft — eight schools that historically shared a common application process and academic standards. These schools remain the most prestigious and academically rigorous boarding schools in the country and are the primary targets for families seeking elite boarding education. All eight are recognized by college admissions officers as preparing students for the most rigorous undergraduate programs. A student admitted to any of these eight schools and who completes their program with strong grades and test scores is very well positioned for selective college admissions.

What should I look for when visiting a boarding school?

A boarding school visit is more revealing than a college visit because the community is self-contained — you can observe academic culture, dorm life, dining, and social dynamics in a single visit. Key things to assess: (1) Classroom observation — ask to sit in on a class in your area of interest; observe whether discussion is student-driven or teacher-driven; (2) Dorm tour with a student — ask the student guide candid questions about dorm culture, student stress levels, and social dynamics; (3) Faculty accessibility — ask specifically how students can reach teachers outside of class; most top boarding schools have faculty living on campus with regular evening availability; (4) Peer community — talk to students who weren't assigned as your guide; a school's culture is best measured by random encounters with students; (5) Academic pressure — ask what percentage of students are on academic probation and how mental health support works; boarding school pressure is real and worth understanding before committing.
