Trade-offs
- !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
- !Ends at Grade 9 — no high school; families must arrange a separate high-school transition (Tokyo or overseas)
- !No IB or Cambridge programme offered (no published authorisation)
- !No published EAL/ESL (English-support) programme on public pages — may challenge non-native-English entrants, especially at older grades
- !Small size means narrower extracurricular/specialist breadth than larger K–12 campuses
- !No published university-placement data (structurally — the school is K–9)
