Strengths

Kennedy International School
  • Long heritage (founded 1964) as one of New York's established bilingual international schools
  • Genuine dual-immersion model — two full bilingual tracks (French-English and Japanese-English), not token language classes
  • Accredited by the French Ministry of Education and in the AEFE network, enabling seamless transfer into the French school system
  • Authorized IB Diploma Programme school since 2014, offering a rare bilingual French/English IB Diploma with Spanish as a second language
  • Continuous pathway from nursery (age 3) through grade 12 on two Midtown Manhattan campuses
United Nations International School
  • 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

Kennedy International School
  • !Holds no US regional accreditation (WASC, MSA, NEASC, or CIS) — its quality assurance runs through the French Ministry and NYSED recognition instead
  • !Publishes no current total enrollment, student-teacher ratio, or class-size data on public pages
  • !Does NOT publish IB Diploma score averages or pass rates — academic outcomes cannot be independently verified
  • !Does NOT publish university-placement or matriculation data
  • !No published, structured EAL/ESL program on public pages, despite an immersion intake (over 50% of elementary students were reported as non-French-speakers prior to enrolling)
United Nations International School
  • !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

University Placement

School-reported · not independently verified

Kennedy International School

School-reported, unverified: Kennedy International School does not publish IB Diploma score averages, pass rates, or a university-placement/matriculation list on its public pages, so senior-school outcomes cannot be independently verified. Its French Ministry accreditation supports transfer into the French school system, but specific university destinations are not disclosed.

United Nations International School

School-reported, unverified: per third-party summary, nearly all graduates attend four-year colleges, with roughly 75%–85% enrolling at universities in the United States and the remainder at universities in about 13 other countries. UNIS does not publish an IB Diploma average score or a specific university-destination list on its own pages; treat placement claims as school-reported and unverified.
