International schools in Thailand

189 internationally accredited schools

The market in brief

The ranking holds 189 schools in Thailand with an international accreditation or an authorised programme. IB programmes at 41 of them. Cambridge, IGCSE and A-Level, at 80. A preschool section at 153. A year of school costs from $134 to $37 928.

2 schools publish a monthly fee rather than a yearly one and do not say how many payments they charge over a school year. We count such a year as ten payments: that is the number charged by the schools that do state it, and that is how long the school year runs in most countries of the ranking.

Thailand next to other countries in the ranking

The median fee for a year of school in Thailand is $15 618. That is 14th for affordability out of 19 countries in the ranking. A comparison only means anything at a single exchange rate, so every figure is converted to dollars from one weekly snapshot.

Turkey$21 23321646%
Israel$29 1881540%

The median is steadier than the average: one school charging three times the rest does not shift it. It is taken from the top of a school's fee range, that is from the senior stage, which is what families budget for. Free state schools are left out of the median, or it would stop answering the question of what you pay.

Most expensive$37 928 a yearShrewsbury International School Bangkok, Riverside Campus

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 Thailand are taken from published price lists, not from what third parties say.

Why some schools in Thailand do not publish a fee

61 % of schools in Thailand name a fee on their own site (115 of 189). Across the whole ranking of 1296 schools it is 35 %. We read every school's site and worked out what schools write instead of a sum, and why openness follows the country and the network rather than the school: the study of school fees →

Private schools in Thailand

185 of the 189 schools in the ranking are private. The other 4 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 Thailand

4 schools with an international accreditation are funded by the state: Satit Prasarnmit International Programme, Mahidol University International Demonstration School, Yothinburana School - International Programme (YBIP), Kaennakhonwitthayalai School. 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 Thailand

A facility counts only when the school names it outright on its own site: a modern campus is not a swimming pool. Swimming pool: 65 schools · Boarding: 32 schools · School transport: 41 schools.

How to compare schools in Thailand

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 Thailand that is 7.4 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 →

Frequently asked questions

How many international schools are there in Thailand?

The ranking holds 189 schools with an international accreditation or an authorised programme: Bangkok - 79, Chiang Mai - 20, Phuket - 12, Samut Prakan - 9, Surat Thani - 9, Chonburi - 8, Nonthaburi - 8, Nakhon Ratchasima - 7, Rayong - 4, Chiang Rai - 4, Pattaya - 4, Udon Thani - 3, Saraburi - 3, Pathum Thani - 2, Hat Yai - 2, Chumphon - 2, Ko Pkhangan - 2, Kkhonken - 2, Kamphaeng Phet - 1, Chai Nat - 1, Nakhon Pathom - 1, Hua Hin - 1, Samut Sakhon - 1, Roi Et - 1, Lampang - 1, Bangbuatkhong - 1, Krabi - 1. Every school says where its accreditation came from: found in a public register, confirmed by a document from the school, or claimed by the school with nothing behind it. We do not hide a claim, but it does not go into the score.

Is an international school in Thailand expensive next to other countries?

The median fee in Thailand is $15 618 a year. That is 14th for affordability out of 19 countries in the ranking. Cheaper: Paraguay, Tajikistan, Kyrgyzstan, Uzbekistan, Georgia, Chile, Azerbaijan, Kazakhstan, Armenia, Argentina, Cyprus, Uruguay, Montenegro. The comparison only holds inside one year: all fees are converted into dollars at one weekly rate.

Are there free schools with an international programme in Thailand?

Our list holds none in Thailand: all 189 schools with an international accreditation charge a fee. If a state school with an authorised programme appears, it will enter the ranking on equal terms with private ones.

How do you check that a school really holds its accreditation?

We look the school up in the public register of the organisation itself. There are ten such registers today: International Baccalaureate, Cambridge International, CIS, NEASC, COBIS, AEFE, MSA (Middle States Association), Cognia, Pearson Edexcel and the network of German schools abroad. The list grows with the geography of the ranking: a new country usually has an organisation of its own. An accreditation found in a register is marked green and goes into the score. One confirmed only by a document from the school is yellow, and weighs less. One claimed in words is red, and the school's accreditation score is then the lowest. Membership of a network or an association is counted apart: a school joins a network, but earns an accreditation, so membership weighs one step lower. That is why a school calling itself international and a school standing in the ranking are two different things.
