Data note (2026-10-06): Official website checked 2026-10-06: full per-grade table published for 2026-2027; figures now from official site. Official-site discrepancy noted 2026-10-06: The combined row's span (2-18) does not hold for SISB Suvarnabhumi, which the school's own fee page shows as Nursery-Primary 6 only; Thonburi is the all-through campus matching the span.
Google reviews
Google removed ratings and reviews for K-12 schools worldwide in April 2025, so no live Google rating exists for this school — and we don't display placeholder scores. For parent opinion, ask the school for its parent association and its latest inspection or accreditation reports.
