Bangkok hosts one of Asia's largest international school markets, with more than 90 verified school profiles in the metro area. For expat families relocating to Thailand in 2026, this scale is both a blessing and a problem: there are dozens of strong options, but choosing between American, British, IB, Singaporean, Japanese and bilingual Thai-English schools can be overwhelming.
This guide walks through the curricula on offer, the leading international schools in Bangkok, what fees realistically look like in 2026, and how to narrow your shortlist before you arrive.
Curricula available in Bangkok
Bangkok offers most major international curricula:
- International Baccalaureate (IB) — strong cluster of authorised schools, including PYP, MYP and Diploma programmes.
- American curriculum (AERO / Common Core) — usually paired with the IB Diploma in the senior years for university flexibility.
- British curriculum (EYFS, IGCSE, A Level) — the largest single cohort in Bangkok, with several long-established UK schools.
- Bilingual Thai-English programmes — for families who plan to stay long-term and want children fluent in Thai.
- Other national curricula — Japanese, Singaporean, French and German systems are all represented.
Top international schools in Bangkok
NIST International School
NIST International School is the only school in Thailand authorised to teach all four IB programmes — PYP, MYP, Diploma and the Career-related Programme. The Sukhumvit campus is the academic benchmark for IB education in Bangkok and consistently produces above-average IB Diploma scores.
International School Bangkok (ISB)
International School Bangkok (ISB) is the city's flagship American-curriculum school, founded in 1951. The 36-acre Nichada campus offers Pre-K through Grade 12 with the IB Diploma in the upper school and is a strong fit for families coming from the United States.
St. Andrews International School
St. Andrews International School is part of the Cognita group and one of the largest British curriculum schools in the city, with multiple campuses across Bangkok. The school covers EYFS through to A Levels with strong pastoral care and a busy boarding option for senior students.
Garden International School
Garden International School follows the British curriculum from EYFS through Year 13. Smaller class sizes than ISB or NIST make it a strong fit for families who prefer a more boutique environment, and the school has expanded its STEAM and outdoor learning programmes in recent years.
D-PREP International School
D-PREP International School is one of Bangkok's newer schools, founded in 2018 with a project-based American curriculum and IB Diploma in the senior years. It is the option to look at if your child responds better to inquiry-led, less traditional classroom formats.
School fees in Bangkok
Fees in Bangkok remain considerably lower than London, Singapore or Hong Kong. Indicative 2026 ranges:
- Top-tier IB and American schools (NIST, ISB): THB 850,000 to THB 1,150,000 per year (around USD 24,000 to USD 32,000).

- Bilingual Thai-English programmes: THB 200,000 to THB 400,000 per year, the most affordable bracket.
- Application and capital fees: THB 5,000 application fee, plus capital levies of THB 100,000 to THB 250,000 in the established schools.
Many multinational employers (oil & gas, banking, automotive) cover schooling under expat packages, so confirm what is included before signing your assignment letter.
Where to live in Bangkok
School location dictates housing for most families:
- Sukhumvit (Soi 31, 39, 49, 63) — central, walking distance to NIST, easy BTS access. Most expats start here.
- Nichada Thani (Pakkret) — gated estate built around ISB; suburban, quiet, family-oriented.
- Bang Na — newer estates and several British schools (Bromsgrove, Ascot Group). Lower rent than central Sukhumvit.
- Sathorn / Silom — central business district, smaller but very accessible, suits families with younger children.
Bangkok traffic is notorious. A school 8 km away can take 60 minutes by bus during rush hour. Always test the school commute at peak times before committing.
Practical admissions tips
- Apply 9 to 12 months ahead of the August start date for the most competitive year groups (Pre-K, Year 7 and IB Diploma entry).
- Most schools run rolling admissions, so mid-year placements are possible if your relocation timing slips.
- Bring apostilled school reports for the last two years and a vaccination record matching Thai requirements.
- Visit at least three schools in person — campuses vary enormously in size, vibe and student demographics.
- Ask for IB Diploma score history and university placement lists for the last three graduating cohorts.
