Thailand has roughly 280 international schools and almost none of them appear in one place with their fees. The schools publish the figures, usually as a PDF each spring, and then the comparison sites copy them with errors and no date. The Baht reads each school's own schedule, records every year group and every one-off fee with the source and the date, converts it to pounds at the mid-market rate, and leaves a blank where the school publishes nothing.

Pound figures use 44.9 THB per GBP (Latest daily mid-market snapshot · 10 November 2026). Schools that do not publish a fee are listed, without a figure, on their city page.
What the fee does not tell you
- The hidden fees catalogue: the £30,000 to £70,000 your school will charge that is not in the tuition schedule.
- The fee inflation trap: how £18,000 in Year 1 becomes £32,000 by Year 13.
- The British family's decision framework for international schools in Asia.
- Where the £25,000 actually goes: the international school operating budget nobody publishes.
School fees are usually the largest single transfer an expat family makes, and they are billed in baht against a sterling income. The send money hub covers how to move termly fees without a bank's spread, and the cost of living hub puts the fee next to rent and the rest of the family budget.
Additions and re-checks are logged by day on what changed.
How The Baht records school fees
Every figure comes from the school's own website or fee document, recorded with its URL and the date it was checked. Annual tuition is recorded as the school states it for the academic year shown; where a school prints termly fees only, the annual figure is the termly fee multiplied by the number of terms and is marked as derived. The headline figure for comparison is Year 7 (or Grade 6) where the school lists it, otherwise the nearest band the school publishes. Refundable deposits are listed but excluded from totals. Fee schedules change every year, mostly between March and July, and each page shows when its figures were last read. Corrections: editorial@thebaht.com.
