- !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
- !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
