Trade-offs
- !'Full IB Continuum' marketing vs. evidence that MYP may be candidate-stage, not authorized — a continuity gap in the middle years
- !Multi-campus, age-split sites (2–6 vs 3–15 vs 15–18) can mean transitions between physical campuses
- !No published verified IB average — only a reported range (27–40); cohort-level outcomes not transparently public
- !Heavily Japanese-connected student body (~65% with at least one Japanese parent) may dilute the international-immersion some expat families expect
- !Accreditation/authorization detail relies partly on a Wikipedia article with maintenance flags
- !No public BSO or ISI inspection rating found — no external inspection band to verify quality, unlike British peers such as Tanglin
- !Accreditation is unclear: COBIS participation is evident, but accredited-membership/BSO status is not confirmed on any public directory
- !Sixth form is mid-transition (A-Levels phasing out by 2026, IB DP ramping up) — no IB results track record yet
- !No EAL support — unsuitable for families whose children aren't already fluent in English
- !Premium fees with annual increases plus sizeable one-time enrolment and resources fees
