Figures are converted to dollars at a weekly rate; schools publish their fees in their own currency. One-off charges, meals, transport and uniform are not included unless the school says otherwise. Fees for schools in Bangkok are taken from published price lists, not from what third parties say.

Private schools in Bangkok

77 of the 79 schools in the ranking are private. The other 2 are state schools, set out below. The type of school does not affect the score: private and state schools sit in one list and are scored by the same formula, and only verifiable data moves the number.

State schools in Bangkok

2 schools with an international accreditation are funded by the state: Satit Prasarnmit International Programme, Yothinburana School - International Programme (YBIP). Admission to these schools is usually competitive, and tuition is free or markedly cheaper than at a private school. In the ranking they stand alongside private schools and are scored on the same nine criteria.

Facilities at schools in Bangkok

A facility counts only when the school names it outright on its own site: a modern campus is not a swimming pool. Swimming pool: 30 schools · Boarding: 11 schools · School transport: 20 schools.

How to compare schools in Bangkok

Comparing schools on a single feature is useless: the most expensive is not the best, and a famous name says nothing about what is backed by documents. The score is therefore built from nine criteria with different weights - from academic programmes and accreditation to facilities, clubs and fees relative to other schools in the country.

A criterion counts towards the score only when there is verifiable data behind it. That is why every score says how many of the nine criteria were counted: at schools in Bangkok that is 7.3 out of 9 on average. A school with a detailed site and a school with no site cannot earn an equally reliable score, and that is shown rather than hidden.

Ratings and reviews from Google Maps, Yandex Maps and 2GIS are not used: their terms forbid aggregation. Only verified reviews left here count. Full methodology →

How do you compare schools in Bangkok?

The score of every school adds up from nine criteria with different weights: academic programmes, accreditation, facilities, clubs, the fee against other schools in the country, reviews, university destinations, safety and teachers. A criterion counts only when there is data behind it that can be checked, so every score says how many of the nine were counted. Right now that is 7.3 out of 9 on average. We do not use reviews from maps or directories.
