Every international school in Thailand — fees & accreditation, verified.

Across the schools in our dataset that publish fees, annual tuition runs from under ฿110,000 to ฿1,276,000. Most Bangkok all-through schools sit between ฿400,000 and ฿900,000 a year; most provincial schools between ฿200,000 and ฿600,000. Genuine sub-฿300,000 options exist in every region — see the benchmark section above and our fees guide.

[O] means we captured the figure from the school's own published fee document. [A] means a third-party aggregator (such as the International Schools Database or Edarabia) lists it — useful for comparison, but never quote it to a school as its official fee. [NV] means no reliable public figure could be verified, so we show no number rather than a guess.

Not necessarily. Membership of an association is not accreditation. Accreditation comes from bodies such as CIS, WASC, NEASC or Cognia after an inspection cycle; the IB, Cambridge and the College Board grant programme authorisations, which are a third, different thing. Our accreditation guide explains how to tell them apart and verify each one.

Start with the destination, not the brand: British (IGCSE/A Level) and IB Diploma both travel well worldwide; an American diploma with AP courses is the natural fit for US applications but is also accepted elsewhere. In Thailand all three are widely available. Our curriculum guide compares structure, exams and switching costs.

Only some. In our October 2026 pass, roughly one third of schools publish a complete fee table, one third publish partial or "from" prices, and one third require an enquiry. Where a school publishes nothing verifiable, its CredRadar page says so instead of estimating.

Because they count different things: the Thai MOE/OPEC licences 249 schools (2024); the ISAT directory lists 207 member entries, counted per campus and including standalone kindergartens; ISC Research counts 180+ "premium" English-medium schools. CredRadar publishes its own reconciliation on the methodology page.
