Thailand International School Fees Report 2026
Every figure below is computed from CredRadar's verified dataset of 170 listed schools — the same records, with the same source labels, that power this directory. Medians use the midpoint of each school's published annual range and include only schools that publish figures. Method: methodology.
The headline: the median listed school charges ฿414,000 a year — and only 75% of schools publish a fee figure we could verify at all.

Transparency
How much of this market publishes its prices?
Of 170 listed schools: 106 (62%) publish fees we captured from their own documents [O]; 23 are carried on aggregator figures [A]; 43 publish nothing we could verify. A directory can only be as transparent as its schools — we label the gap rather than filling it with estimates.
