Bangkok has become one of Asia's most popular destinations for expat families, and the international school market has matured to match. Whether you arrive with a multinational, a regional NGO or simply because Thailand felt right, the choice you make at admissions stage will shape your child's next several years. This 2026 guide for international schools in Bangkok walks you through curricula, fees, top schools and practical tips to take the guesswork out of the decision.
Curricula available in Bangkok
Bangkok offers one of the broadest curriculum mixes in Southeast Asia. Most expat families weigh up four main routes:
- British (IGCSE and A-Level): familiar university pathway for UK-bound students, with strong subject specialisation in the final years.
- American: AP courses combined with US high school diplomas, ideal if your family expects to apply to North American universities.
- International Baccalaureate (IB): the broadest framework, available as PYP, MYP and Diploma. Strong fit for families that move countries every few years.
- Bilingual Thai-English: useful if your stay is long-term and you want your child to be functional in Thai for daily life.
Top international schools in Bangkok
The schools below are widely cited by relocation consultants and have established admissions desks for expat families.
NIST International School
The first non-profit IB world school in Thailand, NIST is one of the most established names in Bangkok. Located in Sukhumvit, it offers the full IB continuum from Early Years to Diploma and counts a long list of universities among its alumni destinations. See the NIST profile on ISA.
International School Bangkok (ISB)
ISB is the largest American-curriculum school in the city, with a 36-acre campus in Nichada Thani. It blends a US high school diploma with the IB Diploma in Years 12-13, giving families flexibility on university applications. View ISB on ISA.
St. Andrews International School
St. Andrews follows the English National Curriculum from Early Years to IGCSE and the IB Diploma in Years 12-13. With three campuses across Bangkok, it tends to be a popular choice for British expat families looking for a familiar pathway. View St. Andrews on ISA.
D-Prep International School
A modern, project-based school that offers the IB framework with a strong emphasis on entrepreneurship and design thinking. The campus in Bangna is purpose-built and a good fit for families who value innovation in pedagogy. D-Prep on ISA.
KIS International School Reignwood Park

School fees and budgeting
Tuition at established international schools in Bangkok in 2026 typically falls in the following ranges (THB per year, before sibling discounts and additional levies):
- Primary years: THB 600,000 to THB 950,000
- Middle school: THB 750,000 to THB 1,100,000
- IB Diploma / A-Level / High School: THB 900,000 to THB 1,250,000
Add capital levies (often THB 100,000 to THB 200,000 one-off), application fees, technology charges, lunch and bus. Most international schools also bill in THB but accept transfers in USD or GBP for overseas families.
Where to live near each school
Bangkok traffic is the silent admissions criterion. Sukhumvit (Phrom Phong, Thong Lor, Ekkamai) keeps NIST and several British schools within reach. Nichada Thani is essentially built around ISB. Bangna and Sathorn are growing residential hubs with good links to several international campuses. If both parents work in the CBD, prioritise schools with a reliable bus route over schools that look nominally closer on a map.
Admissions tips for expat families
- Start six to nine months before arrival. The most popular schools have waiting lists, particularly for Year 7 entry.
- Prepare a full academic file: last two years of reports, MAP or CAT4 if available, language profile and any learning support documentation.
- Confirm the visa angle. Schools sponsor the dependent education visa, but timelines vary. Ask the registrar for a checklist before flights are booked.
- Visit at least three schools in person. The campus walk-through tells you more about culture than any glossy brochure.
