Best IB Schools in New York for International Families

A historic (est. 1872) Manhattan IB World School and genuine U.S. IB pioneer — the first school in the country authorized for the IB Primary Years Programme and the first in the Americas authorized for the full IB continuum — serving ~921 day students from preschool through grade 12 across four Upper West Side campuses. MSA- and CIS-accredited; because the U.S. has no graded public inspectorate, the tier is capped at A.

An independent, non-profit French-and-Spanish dual-language immersion school (est. 2005) in Carroll Gardens, Brooklyn, running the IB Primary Years Programme (Pre-K 3–Grade 5) and Middle Years Programme (6th–8th). NYSAIS-accredited and tied into the French (AEFE/Mlf) and Spanish education networks. Ends at Grade 8 — no high school, no IB Diploma — and, being Pre-K–8, has no exit-exam or university-placement data to publish. Tier capped at A: the US has no graded public inspectorate.

A long-established (est. 1964) Midtown-Manhattan bilingual day school offering French-English and Japanese-English tracks from nursery through grade 12, culminating in a bilingual French/English IB Diploma. Its distinctive strength is genuine dual-language immersion accredited by the French Ministry of Education; its main limits are the absence of a US regional accreditation (WASC/MSA/NEASC/CIS) and no publicly disclosed enrollment, IB results, or placement data.

A premium, downtown-Manhattan IB World School (est. 2005) spanning 12 months through Grade 12 across two Financial District campuses — distinctive as New York City's only school with a residential boarding program, MSA-accredited and NYSAIS-member, with the IB Diploma as its optional capstone.

A small, central-Manhattan British-curriculum day school (ages 3–18) blending the English National Curriculum with IB PYP/MYP in the lower and middle years and a Cambridge IGCSE/A-Level upper school — accredited by COBIS and IB-authorized, but note it does NOT run the IB Diploma and publishes no exam results.

The founding IB school of the United Nations — a large, non-profit, coeducational PreK–12 IB day school in Manhattan (est. 1947) with an exceptionally international community, CIS + NYSAIS accreditation, and a UN-affiliated admissions priority. Tier capped at A: the US has regional/independent-school accreditation but no graded public inspectorate.
