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
- !No published independent inspection (BSO or ISI) — quality assurance rests on accreditation/membership rather than a graded inspection band
- !Total student enrollment is not published, limiting visibility on school size and demand
- !No IB pathway — families wanting the IB Diploma must look elsewhere
- !EAL provision is described as Early-Years immersion; no dedicated, named EAL programme for older entrants is detailed publicly
- !A-Level results, while strong, are school-reported and not externally verified
