What Trinity School does

Trinity School is a private, independent, co-educational K-12 college preparatory day school located at 139 West 91st Street on Manhattan's Upper West Side. Founded in 1709 by the Church of the Holy Trinity, it is one of the oldest schools in the United States, operating under the nonprofit entity The Trinity Episcopal Schools Corp. The school serves approximately 1,040 students across three divisions — Lower School (K-4), Middle School (5-8), and Upper School (9-12) — with a 13:1 student-teacher ratio. Beyond core academics, Trinity offers 22 sports, approximately 40 performing arts performances annually, 8 global engagement trips, 14 community partnerships, and 30 diversity affinity groups. The school operates auxiliary fee-based programs including Trinity Discovery Day Camp, Trinity After School (K-6), Trinity Swim Club, private music lessons, and standardized test preparation in partnership with Zinc Educational Services.

Trinity's technology infrastructure is built on Google G-Suite, Chromebooks for Middle and Upper School students, iPads, and MacOS/Windows computers, supplemented by an Upper School Tinkerspace with 3D printers and sensors, and a Computer Science sequence covering Processing, Java, Python, HTML/CSS/JavaScript, and Arduino. The TigerNet portal serves as the digital community platform for alumni and families.

The school's revenue model combines tuition and fees (billed annually) with a multi-channel philanthropic apparatus that includes the Trinity Fund (annual giving), Reunion Giving Initiative (over $5 million raised since 2017), Alumni Bridge Bricks ($1,709 commitment per brick), matching gifts via Double the Donation, stock gifts via Morgan Stanley, planned giving, and special events including Fall Festival and Spring Fling. Approximately 20% of the student body receives financial aid, with nearly 30% of the school's endowment earmarked for student aid, reflecting a mission-driven commitment to access alongside prestige.

• The Spence School: Elite NYC K-12 independent day school (girls). Trinity co-hosts the Interschool College Night with Spence, and the schools compete for the same pool of high-income NYC families despite Spence's single-sex configuration.
• The Dalton School: Elite NYC K-12 independent day school on the Upper East Side. Trinity collaborates with Dalton on the Interschool College Night; Dalton competes for the same selective NYC applicant pool and runs a comparable college-preparatory program.
• The Brearley School: Elite NYC K-12 girls' independent day school on the Upper East Side. Long-tenured peer in NYC's selective prep market, drawing from overlapping high-income NYC families and competing for similar college-counseling outcomes.
• Chapin School: Elite NYC K-12 girls' independent day school. Operates in the same NYC luxury private-school market segment as Trinity, with comparable tuition, financial aid structure, and college placement profile.
• Ethical Culture Fieldston School: Elite NYC K-12 independent day school in the Riverdale/Riverdale sections. Sister schools (Ethical Culture K-6 and Fieldston 7-12) form a peer of similar size and selectivity serving NYC families.

Emerging players

• Avenues: The World School: Newer elite NYC K-12 independent day school (opened 2012) emphasizing global curriculum and language immersion. Direct overlap with Trinity's Global Engagement and college-prep mission, but on a faster-growth, newer brand.

Broad incumbents

• Phillips Exeter Academy: Premier US boarding/day secondary school (9-12, plus PG) with substantially larger endowment and broader national applicant pool. Comparable academic positioning and college placement, but operates a residential model outside NYC rather than competing head-to-head in NYC.
