International Schools in Chiang Mai: a parent's guide

Why Chiang Mai for international education

Chiang Mai has quietly become one of Thailand's most attractive places to raise and school a family. It offers much of what Bangkok does — established international schools, well-recognised curricula and a globally minded community — but with a cooler, greener setting and a noticeably lower cost of living.

That combination is why the city is so popular with expat, relocating and remote-working families. Housing, everyday costs and, crucially, school fees tend to sit below Bangkok levels, while the mountains, slower pace and outdoor lifestyle are a large part of the appeal. For families who can work or study flexibly, Chiang Mai often delivers a similar education at a gentler price and pace.

The main international schools

Chiang Mai's international sector is smaller and more close-knit than Bangkok's, which many families see as a feature rather than a limitation. A handful of well-established schools cover the major curricula between them. The profiles below are a general guide — confirm current programmes, year levels, campuses and fees with each school directly.

• Prem Tinsulanonda International School — widely regarded as the city's most prestigious. It runs the full International Baccalaureate (the PYP, MYP and Diploma Programme), offers both boarding and day places, sits on a green campus in Mae Rim north of the city, and is known for a strong outdoor-education and sustainability focus. It is also the priciest school in Chiang Mai.
• Grace International School (GIS) — established in 1999, teaching Kindergarten through Grade 12 on an American curriculum with Advanced Placement (AP) courses.
• Lanna International School — a British-curriculum school following IGCSE and then A-levels, the familiar England-and-Wales academic route into international universities.
• Nakornpayap International School (NIS) — established in 1993, with a US-based curriculum aligned to the Common Core and Advanced Placement (AP) in Grades 11–12, set on a leafy campus in the San Phisuea area.
• Chiang Mai International School (CMIS) — one of the city's longest-established international schools, and a long-standing option for local and expat families alike.

Curricula: IB, British or American

Between them, Chiang Mai's schools cover the three curricula most international families look for, so the first real decision is which route fits your child — not which school has the biggest name. All three lead to qualifications that international universities understand and respect; there is no single best one.

As a rough map of who offers what in the city: Prem is the IB school, Lanna is the British (IGCSE and A-level) school, and Grace and NIS follow American-style programmes with Advanced Placement. Match the curriculum to how your child learns and where you hope they will study next.

• International Baccalaureate (IB) — a broad, inquiry-led programme from the PYP through to the Diploma; offered at Prem.
• British — the English National Curriculum leading to IGCSE and then A-levels, with deep specialisation in the final years; offered at Lanna.
• American — a high-school diploma with Advanced Placement (AP) options and continuous assessment; the model at Grace and NIS.

Boarding options

Most international schools in Chiang Mai are day schools, but the city has a genuine boarding option in Prem Tinsulanonda, which offers boarding alongside day places within its full IB programme.

Boarding can suit relocating families who are still settling, families based outside the city or elsewhere in the region, or students who want the full residential experience that comes with an IB campus built around outdoor and community life. If boarding matters to you, confirm the year levels it is available for, the pastoral arrangements and current boarding fees directly with the school.

Fees to expect

One of Chiang Mai's biggest draws is that international education here generally costs less than in Bangkok, where premium schools can pass ฿1 million a year. As of the 2025–2026 school year, Chiang Mai fees span a wide range — roughly ฿140,000 to ฿650,000+ a year (about USD 4,000–18,000+) — depending on the curriculum, the school and the year level. Treat these as approximate and verify the current schedule with each school.

Fees rise with year level and usually exclude one-off registration, EAL or learning support, and external exam fees (IGCSE, IB or AP) in the exam years, so budget for the all-in figure rather than the headline tuition alone.

• Budget and bilingual programmes — from around ฿140,000 a year (approx., 2025–2026).
• Mid-range British and American schools — roughly ฿200,000–฿420,000 a year (approx., 2025–2026).
• Prem Tinsulanonda (full IB, with boarding) — the highest in the city, up to around ฿600,000–฿750,000+ a year (approx., 2025–2026), before boarding and extras.
• On top of tuition, plan for registration, deposits, EAL where needed, exam fees, uniforms, buses and annual increases.

How to shortlist a school

With a manageable number of schools, Chiang Mai is a city where families can realistically visit their whole shortlist. Start from the curriculum and your budget, then let campus visits and university outcomes settle the final choice.

Look past the brochure: ask each school for its recent university destinations, the spread of IB scores or A-level and AP results, class sizes, and how it supports children who are still building their academic English. The best fit is the school that matches your child and your goals — not automatically the most expensive or the best known.

The English factor: the gate to upper years and universities

Every international school in Chiang Mai teaches in English, and English works as a quiet gatekeeper twice over. Entry into the upper years usually requires a proven level of academic English, and admission to international universities generally asks for IELTS or TOEFL — with IELTS Academic the most widely accepted test worldwide.

So strong academic English is not optional; it is what unlocks both a school's senior years and the universities the whole plan is aimed at. Building it early, alongside school, protects the return on everything else you are paying for. This is where engforedu.com fits in honestly: it offers bilingual (Thai and English) IELTS and English practice with AI band scoring on Writing and Speaking against the official criteria — a low-cost way to keep a child's English on track for those gates, not a replacement for school.
