Strengths
- ✓True 2–18 continuity on one campus (Foundation Stage → IB Diploma), confirmed publicly
- ✓CIS accreditation and authorised IB World School — dual, independently verifiable institutional anchors
- ✓Genuine non-profit foundation governance (no shareholders; volunteer board) — verifiable, not marketing
- ✓Strong published 2025 IB outcomes (99% pass, avg 35) and IGCSE results
- ✓Dedicated EAL ('English as an Additional Language') staffing plus Home Languages and Inclusion programmes
- ✓Full IB continuum (PYP + MYP + DP) — first and longest-established full IB World School in Thailand (since 1992)
- ✓Dual CIS + NEASC international accreditation — strong external quality assurance in a country with no public inspectorate
- ✓Published IB DP average of 37 with a 100% pass rate (school-reported but specific and consistent)
- ✓Genuine not-for-profit, parent-governed foundation model — fees reinvested, not extracted
- ✓Strong language inclusion: EAL/English Language Support, World Languages, 12 home languages, 56% bilingual-diploma graduation rate
Trade-offs
- !No published external inspection band (no BSO/ISI report) — assurance rests on CIS/IB accreditation alone, a weaker anchor than an inspected Outstanding rating
- !Very large (~2,300 students) — may feel impersonal to families wanting a small-school environment
- !Premium fees (up to ~THB 1M/year) place it among Bangkok's most expensive options
- !Curriculum switches from English National Curriculum/IGCSE to IB at sixth form — families specifically seeking A-Levels won't find them here
- !Cambridge vs Edexcel IGCSE board not clearly stated publicly
- !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

University Placement
School-reported · not independently verified
