What The Dalton School does

The Dalton School is a private, nonprofit, co-educational K-12 day school founded in 1919 by Helen Parkhurst in New York City, operating from three campuses on Manhattan's Upper East Side (108 East 89th Street, 53 East 91st Street, and 200 East 87th Street, including a 32,000 sq ft Physical Education Center). It serves approximately 1,330 students across three divisions—First Program (K-3), Middle School (4-8), and High School (9-12)—with selective admissions requiring applications, testing, essays, interviews, and mission alignment. The school's core differentiator is the Dalton Plan, a progressive pedagogical framework structured around three pillars: House (community), Assignment (empowered learners), and Lab (collaborative exploration), supported by 88% of faculty holding advanced degrees.

The school's product surface extends well beyond core academics to include a nationally recognized chess program (established 1987, producing 6th Grade and High School National Champions), 50+ interscholastic athletic teams with 102 league championships, 28 annual main-stage productions, 75+ high school and 50+ middle school clubs, 70+ after-school enrichment programs for K-6, Dalton Global Initiatives with trips to 15+ countries, K-12 service learning, internships, college counseling, and a portfolio of summer camps. Revenue is generated through annual tuition exceeding $70,000 per student (placing Dalton among the most expensive NYC private schools, alongside Spence, Nightingale-Bamford, and Avenues), supplemented by an Annual Fund that has raised $25 million cumulatively, a $108 million Centennial Campaign that added $20 million to endowed funds, the Spring Benefit, Senior Class gifts, and the Warren Hines '88 Scholarship Fund. The school is FERPA-compliant and a member in good standing of the Ivy Preparatory School League and NYSAIS.
