Trade-offs
- !Accreditation transparency is weak: WASC/CIS status is not verifiable from public pages (logos render as placeholders); only GSF membership is confirmable
- !No published IB Diploma average or examination results — academic outcomes cannot be independently assessed
- !No public university-placement/matriculation data
- !Enrolment size not disclosed publicly — hard to gauge cohort scale or community depth
- !High fees (up to ~KRW 35.3M) with limited public outcome data to justify the premium
- !Explicit Christian-faith ethos with required Bible instruction and weekly chapel — a defining fit consideration for non-Christian or secular families (stated as a feature, not a judgement)
- !No IB pathway — families wanting IB DP must look elsewhere; AP is the only advanced track
- !No published IB average / externally verified academic-outcome metrics (AP results not public)
- !Fees are high (~KRW 30–35M/year) at the upper end of the market
- !No public school inspectorate in South Korea — quality signal limited to accreditation, capped at A
