International Schools in Bangkok: The Complete Guide

Bangkok is one of the world's great expat cities, and its international school sector reflects that status. With dozens of accredited international schools offering British, American, IB, and other curricula at a range of price points, families moving to Bangkok generally have excellent educational options. The challenge is navigating a market that can appear bewildering from the outside. This guide provides a structured overview.

The Bangkok International School Landscape

Bangkok has over 60 international schools catering to its large and diverse expatriate population. Schools range from small community institutions serving specific national groups to large, well-resourced campuses with thousands of students, international sports facilities, and sixth form or pre-university programmes.

Unlike Dubai, there is no single government inspectorate publishing comparable ratings for all schools. Accreditation bodies play a key role: schools may hold accreditation from the Council of International Schools (CIS), the Western Association of Schools and Colleges (WASC), the New England Association of Schools and Colleges (NEASC), or national curriculum bodies. Accreditation does not guarantee quality, but its absence is a warning sign.

Curriculum Options

British Curriculum

British curriculum schools in Bangkok follow the UK National Curriculum, leading to IGCSEs and A-Levels (or IB Diploma as an alternative at some schools). This is the preferred route for British families and a common choice for families anticipating eventual return to the UK or applying to UK universities. Examples: Shrewsbury International School, Harrow International School Bangkok, Rugby School Thailand, British International School Bangkok (BISB).

American Curriculum

US curriculum schools follow K-12 programmes leading to the American High School Diploma with AP courses or IB. Preferred by American families and those planning US university applications. Examples: International School Bangkok (ISB) — one of the most established American curriculum schools in Asia; Ruamrudee International School.

International Baccalaureate

IB is offered at several schools, either as a standalone curriculum (PYP, MYP, DP) or as a sixth form option alongside a British curriculum lower school. The IB Diploma is respected globally for university entrance. Examples: Wells International School, ISB offers IB, NIST International School.

French Curriculum

The Lycée Français de Bangkok operates under the French national curriculum (AEFE network), serving the substantial French expatriate community and French-speaking families. Instruction is primarily in French.

Bilingual and Other Curricula

Several schools offer bilingual programmes (Thai-English) or serve specific national communities. These are often less portable internationally but can be a valuable choice for families with long-term Thailand plans and children who benefit from Thai language immersion.

Top Schools: A Selective Overview

Shrewsbury International School Bangkok One of Bangkok's most prestigious international schools, the Bangkok campus of the English public school. British curriculum through to IGCSE and A-Levels, exceptional facilities on a large riverside campus. Consistently in demand and selective on entry. High fee point.

Harrow International School Bangkok Another UK public school brand with a Bangkok campus. British curriculum, boarding available for older students, strong academic and extracurricular reputation.

International School Bangkok (ISB) A large, well-established American curriculum school in Nichada Thani (northern Bangkok), popular with US-affiliated families and corporates. Large campus, strong sports and arts programme, IB DP available alongside AP.

NIST International School IB curriculum throughout (PYP, MYP, DP), located in the Asoke area. Well regarded for academic rigour and diversity. Smaller than ISB, strong community feel.

Bangkok Patana School One of Bangkok's oldest international schools, British curriculum, located in Phra Khanong on a large campus. IB DP available. Highly regarded by the British community, strong alumni network.

Rugby School Thailand A newer campus (opened 2017) of the UK's Rugby School, in Bang Lamung (Chonburi province, on the Eastern Seaboard towards Pattaya). British curriculum, boarding available, strong extracurricular programme.

Wells International School An established IB school with campuses in central Bangkok (Thonglor) and Bangna. Accessible fee point relative to the premium schools.

St Andrews International School Multiple Bangkok campuses (including Sukhumvit and Bangna), British curriculum. Popular and well-established, slightly less exclusive than Harrow or Shrewsbury.

Fee Ranges

International school fees in Bangkok are lower than Dubai or Singapore but still represent a significant household expense:

• Lower-cost international schools: THB 200,000–400,000 per year (approximately £4,500–9,000)
• Mid-range international schools: THB 400,000–700,000 per year (£9,000–16,000)
• Premium schools (Shrewsbury, Harrow, ISB): THB 700,000–1,100,000+ per year (£16,000–25,000+)

These are approximate tuition fees for 2025–26 and exclude registration fees (typically THB 50,000–200,000, often one-time), bus transport, meals, uniforms, extracurricular activity fees, and school trips. All-in budgeting should add 15–20% to headline fees.

Unlike Dubai, Bangkok school fees are generally denominated in Thai Baht, reducing direct currency volatility if your income is in GBP or USD when the Baht is relatively stable — though exchange rate movements remain a real consideration for budgeting.

Admissions Process

Application Timeline

Most Bangkok international schools run a September–June academic year in line with Western systems (some run August–May). The main entry points are:

• September intake (primary age, age 3–11): Applications typically open October–January for the following September
• Secondary entry (age 11–16): More selective; earlier application is advisable
• Sixth form entry (age 16+): Requires GCSE results and may involve interview

Premium schools such as Shrewsbury and Harrow have waiting lists for Foundation and lower primary. Families planning a Bangkok relocation 12–18 months ahead should apply as early as possible.

Documents Typically Required

• Completed application form
• Recent school reports (last 2 years)
• Passport copies
• Immunisation records
• English language assessment (for non-native speakers)
• Teacher references (secondary age)

Assessment

Most schools conduct informal or formal assessments. At primary level this is typically a visit/observation day. At secondary, expect tests in English and Mathematics, sometimes Science. English language proficiency is assessed for non-English-dominant students; EAL (English as an Additional Language) support is available at most schools.

Location and Transport

Bangkok's traffic is genuinely challenging. School location relative to home is important. Key school clusters map roughly onto expat residential areas:

• Sukhumvit corridor (BTS Skytrain): Several schools accessible from major expat residential areas — Thonglor, Ekkamai, On Nut. Wells Bangkok International School, NIST, and several others are in this zone.
• Nichada Thani (Ngam Wong Wan / northwestern Bangkok): ISB is located here, in a gated community popular with American expats. This area is well served by ISB's own busing network.
• Phra Khanong / Bangna (eastern Bangkok): Bangkok Patana. Good motorway access for families in eastern Bangkok or near the Eastern Seaboard. Rugby School Thailand sits further out on the Eastern Seaboard (Bang Lamung, Chonburi), better suited to families based towards Pattaya.
• Riverside (Charoennakorn / Pin Klao): Shrewsbury's main campus — riverside and relatively removed from the Sukhumvit centre; public school buses available.

Most schools operate their own bus services covering major expat residential areas, with fees typically in the range of THB 40,000–90,000 per year per child.

Questions to Ask at Open Days

• What is the school's accreditation and when was it last reviewed?
• What university destinations do recent IB/A-Level graduates achieve?
• How does the school handle mid-year admissions?
• What is the student population by nationality?
• What EAL or learning support is available?
• What are the fee increase policies?
• What extracurricular options are available?

Financial Planning Considerations

• Employer education allowances: Many international employers and embassies provide education allowances. Know the cap and ensure you choose a school within or close to that allowance.
• Baht denomination: Fees are in Thai Baht; if your salary is in GBP, USD, or EUR, budget for exchange rate movements.
• Fee trajectory: Annual increases of 3–7% are common at premium schools.
• Multiple children: Two children at a premium Bangkok school can cost THB 1.5–2 million per year in tuition alone.
