Trade-offs
- !Tuition is not published on the official website — fee transparency relies on third-party databases (verify directly)
- !No public government inspection rating exists for Thai schools, so external validation depends solely on accreditation
- !IB average (37) and pass-rate figures are school-reported, not independently audited
- !Single-curriculum (IB only) — no A-Level / AP / national alternative
- !Conflicting public founding date ('Since 1999' tagline vs 1992 actual founding) creates minor data ambiguity
- !No published BSO/ISI inspection report — no independent verbatim quality band
- !Academic results and placements are school-reported, not externally audited
- !Premium fees (up to ~THB 1.2M/yr) place it at the top end of the Bangkok market
- !Official fees page not publicly retrievable at the standard URL — fee figures sourced from a third party, should be confirmed
- !Large enrolment (~1,800–2,000) may not suit families seeking a small-school feel
