Strengths
- ✓Established since 2006 with a genuine British/Cambridge identity in the heart of Manhattan (Kips Bay, on the East River)
- ✓Accredited by COBIS and authorized as an IB World School (PYP + MYP), plus a Good Schools Guide International listing
- ✓Documented EAL/English-language support from Nursery through Year 9 (small-group pull-out and in-class) — strong fit for non-native English families
- ✓Small, personal scale: school-reported ~1:7 ratio and classes of roughly 14–18, students 'known by name'
- ✓Full continuous 3-to-18 pathway on one campus, with rolling/mid-year admissions
- ✓Founding IB school (one of the IB's pilot schools) and among the first to award IB diplomas — deep, credible IB pedigree
- ✓Exceptionally international community: roughly 97–109 nationalities among students and 86–91 mother-tongue languages
- ✓CIS accreditation plus NYSAIS membership and long institutional history (since 1947)
- ✓Strong multilingual programme — every student studies French or Spanish from the early years, adding a third language from Grade 7; nine languages offered
- ✓Single continuous PreK–12 pathway (ages ~4–18) on one Manhattan campus culminating in the IB Diploma
Trade-offs
- !Does NOT offer the IB Diploma — IB authorization covers PYP and MYP only, and the Upper School switches to Cambridge A Levels, so the 'IB' framing is a lower/middle-years method, not a Diploma outcome
- !No published IGCSE or A-Level results — academic outcomes cannot be independently verified
- !The ISI inspection on file dates to 2010 and no graded verdict is quoted; COBIS/IB give accreditation but not a public quality band
- !Relatively young Upper School (first Year 10 in 2018, first graduates 2021) — limited senior-school track record
- !No financial aid or scholarships are advertised, against premium fees (up to ~$67,800/year plus one-time enrollment and deposit costs)
- !Does NOT publish IB Diploma average scores or a verified university-destination list — academic outcomes cannot be independently verified
- !Enrollment figures are inconsistent across the school's own pages (cited variously as ~1,427, ~1,450, ~1,454 and ~1,545), so no single precise number is reliable
- !Only the IB Diploma Programme is evidenced — no PYP or MYP authorization is stated, despite a continuous PreK–12 structure
- !EAL/English-language-support provision is not described on public pages and cannot be confirmed
- !The former Queens (Jamaica Estates) K–8 campus closed in 2022, so the school now serves one Manhattan location only
Best Fit For
- • Families in or relocating to New York wanting a British/Cambridge (English National Curriculum → IGCSE → A-Level) pathway

- • UN-affiliated and diplomatic families relocating to New York (who receive admissions priority)
- • Internationally mobile, multilingual families wanting a genuinely global IB community
- • Families seeking a continuous PreK–12 IB pathway culminating in the IB Diploma (including bilingual diplomas)
- • Households prioritising a strong second/third-language programme from the early years
