Which is the best international school in Thailand?
There is no single best international school in Thailand. The right one depends on the curriculum you want, your child's age and where you will live. Settle those three points, then visit two or three schools. A good fit matters more than a famous name.
Your move is set for August, and the school places are not yet. This is the order that works.
International School Bangkok (ISB) is the oldest. It was founded in 1951 as the first international school in Thailand, the US State Department says. It teaches ages 3 to 18 and has 1,822 students. Bangkok Patana School offers a British curriculum, IGCSE and the IB. NIST International School offers the full IB programme (PYP, MYP and DP). Shrewsbury International School Bangkok teaches IGCSE and A Levels (each school's own website, checked November 2026).
Apply six to twelve months before the move, because popular year groups fill early. Ask each school about class sizes, waiting lists and support for children new to English. Most ask for past school reports and a short entry assessment.
How much does international school in Thailand cost?
Fees vary widely by school and grade. At ISB, 2026-27 tuition runs from ฿659,000 a year for Pre-K to ฿1,197,000 for Grades 9 to 12. That is from the school's fee schedule. Grades KG to 5 cost ฿1,015,000 and Grades 6 to 8 cost ฿1,137,000.
Add the one-off and yearly fees. ISB charges a ฿4,700 application fee, a ฿260,000 registration fee in the first year and an annual fee of ฿22,000. Other schools use the same structure under other names, such as an enrolment fee or a capital levy.
Other leading schools sit in a similar band. For 2026-27, Bangkok Patana School's tuition starts at ฿515,000 for Nursery, and NIST International School charges ฿650,200 to ฿1,132,800, the Board of Investment says. Get every school's full fee schedule in writing. Budget for uniforms, buses, lunches and clubs too.
British, American or IB: which curriculum?
Most international schools in Thailand follow one of three systems. British schools teach IGCSE and then A levels. American schools award a US high school diploma, often with Advanced Placement (AP) courses. IB schools offer the Primary Years, Middle Years and Diploma Programmes.
Universities around the world accept all three. A levels suit students who want to focus on three or four subjects early. The IB Diploma suits a broad spread of subjects. The American route keeps choices open until late. If you may move again, pick the system your next country uses, so your child switches with less disruption.
Where do American kids go to school in Thailand?
Many American families choose International School Bangkok, which the US State Department describes in its 2026 fact sheet. ISB is an independent, nonprofit, coeducational day school from Pre-K to Grade 12. Its year runs from about mid-August to early June. Other American-curriculum schools exist; visit before you decide.
Bangkok areas and school runs
In Bangkok, live close to the school. Peak-hour traffic is heavy, and a long drive twice a day wears children out. Many families choose a home a short drive from the campus. Others live along Sukhumvit, Thonglor or Bang Na, near the schools there.
Pick the school first and the home second. Drive the route at school time before you sign a lease: a short distance on the map can take a long time at 7am. Our guide to property in Bangkok explains the main areas. A private driver for the school run keeps the daily trip calm and safe.
Schools outside Bangkok
Thailand has 151 international schools outside Bangkok, OPEC says. Phuket, Chiang Mai, Pattaya and Hua Hin all have British, American or IB options. Families there trade the city for space and shorter school runs. British International School, Phuket teaches IGCSE in Years 10 and 11. Prem Tinsulanonda International School in Chiang Mai was the first in Thailand to offer all four IB programmes. Regents International School Pattaya offers A Levels or the IB Diploma at 16. Hua Hin International School teaches the National Curriculum for England and the IB Diploma (each school's own website or account, checked November 2026).
Accreditation and how to check a school
Check who accredits the school. The Council of International Schools (CIS) and WASC are international accreditation bodies, CIS says. The IB authorises schools to teach its programmes but does not accredit them. Get the school's latest accreditation report and read it before you apply.
Ask too how long the current head has been in post, and how many teachers leave each year.
Can Americans go to school in Thailand?
Yes. Children of any nationality can study at international schools in Thailand. They use a Non-Immigrant ED visa. A parent or guardian with them uses a Non-Immigrant O visa, the Ministry of Foreign Affairs says. LTR families can add a spouse and up to four children under 20. See our LTR visa guide.
