Which should you choose?
Both run IB, so the difference is inspection rating, boarding, and fees rather than the curriculum itself; Léman Manhattan Preparatory School offers boarding while the other is day-only. The choice comes down to target curriculum, whether you need boarding, and budget — verify fees against each school's own figures.
Neither Dwight School nor Léman Manhattan Preparatory School sits in a market with a public inspectorate, so both are assessed on verifiable accreditation, curriculum authorisation, and published data rather than an official quality rating. One practical difference: Léman Manhattan Preparatory School offers boarding while the other is day-only — decisive for families who need a residential option. Verify current fees against each school's own figures (see the table below).

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
