Trade-offs
- !Does NOT publish an IB Diploma score average or a verifiable university-placement record — outcomes cannot be independently confirmed
- !The 'all four IB programmes' marketing claim is not independently verifiable for the Career-related Programme (CP) — only PYP/MYP/DP are clearly evidenced
- !Premium day-school fees (top of scale ~$69,950 for Grades 1–12), placing it among Manhattan's most expensive
- !Accreditation detail is confirmed only via site logos, not a directly cited accreditor listing
- !Day school only — no boarding in New York
- !Does NOT publish IB average scores or a verified university-destination list — the headline '80% accepted to highly selective colleges' is school-reported and unverifiable
- !Full IB PYP/MYP continuum is claimed by third-party directories but NOT confirmed on the school's own pages, which describe only an 'IB approach' culminating in the DP
- !Among the most expensive schools in the sample — Kindergarten–Grade 10 at USD 70,700 and Grades 11–12 at USD 72,000 for 2026-27
- !Boarding tuition is not published on the official site (third-party directories cite figures near USD 89,000–95,000 all-in, unverified)
- !The only public enrollment figure (~750) is a 2016-17 third-party number; no current official total is published
