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
- !No IB pathway — purely AP/American, less flexibility for IB-seeking families
- !Non-Korean residency/citizenship requirement excludes many local families
- !AP exam results / pass rates are not published publicly
- !EAL/ESL support not described publicly despite an English-only environment — unclear provision for non-native speakers
- !Seongnam location is outside central Seoul (a commute consideration)
Best Fit For
- • Families committed to a pure IB pathway from early years through Diploma
