When I was growing up in Chiang Mai, you could count the international schools on one hand.
My older brother went to Chiang Mai International School — the very first international school in the city, founded in 1954 to serve the children of missionaries. My sister and I were enrolled at Nakornpayap International School, back on its old campus. I distinctly remember when NIS was working toward its WASC accreditation — a big deal at the time. And I remember when Lanna International opened, because suddenly there were enough schools in the city to host our own inter-school soccer tournament.
That was then. Today, within a five-minute drive of where we live in Hang Dong, there are nine different international schools. We can walk to several of them. And that's just one corner of one district. Across the city, there are close to 20 international schools — and that number is still growing.
So if you're moving to Chiang Mai with kids who need an international education, you're well covered. The harder problem isn't finding a school. It's figuring out which one is right for your family.
This article isn't going to go deep — we'll leave the exhaustive guides to the seasoned experts who've spent years on it (and point you to the annual international schools fair, where you can explore in person). What this is: an orientation. A lay of the land. The kind of overview that gives you enough context to start asking the right questions.
A brief history of international education in Chiang Mai
Chiang Mai's international school scene has surprisingly deep roots. Chiang Mai International School (CMIS) has been operating since 1954, founded by missionaries from the Church of Christ in Thailand to serve the children of international Christian workers — a demographic that still makes up a significant portion of Chiang Mai's expat community today. For decades, it was essentially the only option.
Nakornpayap International School (NIS) followed in 1993 as the city's first secular international school, and Lanna International opened around the same time. Later in the '90s, Grace International joined the picture with a similar mission-driven focus to CMIS.
That cohort of founding schools served Chiang Mai for years while the city remained a relatively quiet northern outpost. The expansion accelerated in the 2010s as Chiang Mai emerged as a hub for digital nomads, remote workers, and families seeking an alternative to Bangkok's cost and density. Growth has also been driven by increasing demand from Thai families choosing international education over traditional private schools. The result: a market that's roughly quadrupled in school count over three decades and is still adding options — Mill Hill International opened its first year in 2025.
Understanding the curricula
Before you look at a single school, you need a working understanding of the curriculum systems. This is the first and most important filter.
British / Cambridge
The most common curriculum in Chiang Mai. Students work toward Cambridge qualifications: IGCSEs (ages 14–16) and A-Levels (ages 16–18), recognised by universities worldwide. British-curriculum schools tend to emphasise analytical writing and depth over breadth. If your child may return to the UK or attend a UK university, this is the natural fit. American and European universities accept it widely.
American / AP
Follows US standards, typically culminating in Advanced Placement (AP) courses in high school. Broader and somewhat less specialised than British A-Levels — students take more subjects through their senior year. If your family is US-based and your child will likely enter the American university system, this is the cleaner path. CMIS, NIS, Grace, and APIS are the main American-curriculum schools in Chiang Mai.
IB — International Baccalaureate
A Swiss-designed curriculum with three programs: the Primary Years Programme (PYP, ages 3–12), Middle Years Programme (MYP, ages 11–16), and the Diploma Programme (DP, ages 16–19). The IB Diploma is recognised by universities globally and known for academic rigour and a genuinely international outlook — the curriculum of choice for highly mobile families with no strong tie to a single national system. Note: a full IB continuum (PYP through DP) is rare; verify which programs a school is actually authorised to offer.
Chinese-emphasis / trilingual
Worth flagging as its own category given Chiang Mai's growing Chinese expat population. ACIS (Americana Chinese International School) and SISB (Singapore International School) both offer Chinese as a core language alongside English and Thai — not as an elective, but woven into the academic program. ACIS is an official HSK and YCT Chinese proficiency test center. SISB follows the Singapore national curriculum, which itself has a strong Mandarin component. For Chinese families who want their children to maintain language proficiency while earning an internationally recognised qualification, these are the most natural fits in the city.
German curriculum
Chiang Mai Deutsche Schule (CDSC) is the only German-curriculum school in northern Thailand, operating since 1994 in partnership with the German embassy, and holds the "Excellent German School Abroad" designation. If you're a German-speaking family with plans to return to the German system, this is your option.
French curriculum
Windfield International operates a French national curriculum school for ages 2–12. If you're a French-speaking family or planning a return to France, it's the only option in the city — and it only goes to primary level, so you'll need a plan for secondary.
Singapore curriculum
SISB Chiang Mai follows the Singapore national curriculum in the primary years before transitioning to Cambridge IGCSE and A-Levels at secondary. The Singapore curriculum is rigorous, particularly in mathematics, and widely respected for university pathways across Asia.
Bilingual / Thai-English
Several schools operate bilingual programs that blend Thai and English instruction. These follow more of the Thai national curriculum with international elements layered on — fees are considerably lower. Worth considering if your children are young and you plan a long stay, or if budget is a real constraint. Ambassador Bilingual Academy and Tonkla School are the main examples in this category.
Many schools blend more than one curriculum, so the directory below groups them by their primary academic pathway.
Where are the schools located?
Most international schools in Chiang Mai are located south and southwest of the Old City, spreading out into the Hang Dong, Mae Hia, and Saraphi districts. This matters practically — if you're choosing a neighborhood, school location should be a major factor in where you rent. Our guide to the best neighborhoods for expat families explains why Hang Dong in particular has become the default choice for families with school-age kids, and covers Tha Sala and San Phi Sua as well.
If you want to explore school locations on a map alongside other family-friendly amenities — moobans, hospitals, markets, cafes — our free Chiang Mai Relocation Map Pack has all of it in one place.
A few worth flagging geographically:
- Hang Dong / Nong Kwai corridor: SBS International, BCIS, Grace, Panyaden, APIS — the heaviest concentration of international schools in the city
- San Phi Sua / northeast: Lanna, NIS
- Saraphi / Superhighway east: ACIS, UCIS, CMIS
- Near the Old City: SISB (Si Phum district)
- North of the city: Prem Tinsulanonda — a beautiful campus in the Mae Rim hills, but notably further from most expat residential areas; factor in the commute
- Doi Saket / northeast ring road: Mill Hill International
Bus availability varies and is not universal. Always confirm with the school directly.

Fees shown are annual tuition ranges for the 2025/2026 academic year where available, sourced from school websites and the International Schools Database. These are tuition only and don't include one-time enrollment or registration fees, which typically run ฿50,000–฿200,000+. Always verify directly with the school — fees change annually and vary by age group.
American curriculum
One of Chiang Mai's oldest and most established schools, founded in 1954. American curriculum, K–12, with a Christian heritage — all faiths welcome. WASC-accredited, a member of EARCOS and NAIS, with AP courses and rigorous university preparation.
Annual tuition: ฿289,400–฿491,300 (~$8,500–$14,500)
Founded 1993 — the oldest secular international school in Chiang Mai. American curriculum, Kindergarten through Grade 12, WASC-accredited through 2032. The school has grown considerably since its early days and relocated to a spacious 17-acre campus in San Phi Sua on the Second Ring Road. Strong AP and STEM offerings, 619 students from 25+ nationalities.
Annual tuition: ฿290,000–฿496,800 (~$8,500–$14,600)
A large, faith-based school on a 37-acre campus serving 500+ students from missionary and international Christian worker families across 40+ countries. American curriculum, K–12, WASC and ACSI-accredited. What makes Grace operationally unusual: non-Thai teaching staff raise their own financial support through missions organizations rather than drawing a school salary — a model that keeps tuition meaningfully lower for qualifying families, and means every teacher is there by genuine calling. Tuition is fully waived for children of full-time staff, up to three students per family.
Annual tuition: Contact school (ICW family discounts and a Financial Assistance Program available)

The newest and most talked-about addition to Chiang Mai's school scene (opened September 2025). Mill Hill is a prestigious London independent school founded in 1807 — in British terms a "public school," which confusingly means elite private. This is its first campus outside the UK, built in partnership with Ornsirin (Chiang Mai's largest property developer) as part of the Ornsirin City Park development on the Third Ring Road. Currently Nursery through Year 6, with phased expansion to Year 13 planned by 2029 — worth knowing upfront if you have teenagers now. Fees sit at the premium end of the Chiang Mai market.
Annual tuition: ฿447,300–฿516,600 (~$13,200–$15,200) Nursery–Year 4, plus a ฿150,000 placement fee

A full IB World School with all four programs, including the rare Career-related Programme. Boarding and day school, ages 2.5–18, on a 100-acre campus in the Mae Rim hills north of the city. Graduates regularly place at Ivy League and top global universities. The campus is notably isolated — factor in the commute if you're not boarding.
Annual tuition: ฿400,000–฿900,000 (~$11,800–$26,500)
IB + British curriculum
A genuinely distinctive school. British curriculum with the IB Diploma at senior level, layered onto a Buddhist values framework and a sustainability ethos. Bamboo architecture, organic gardens, and a considered philosophy around child development — the 12 Wise Habits framework runs through everything. Ages 2–18. Families either connect with the approach or they don't; worth a campus visit either way.
Annual tuition: ฿303,000–฿571,000 (~$8,900–$16,800)
Montessori
Esara International School and Chiang Mai Montessori International School operate as a connected pathway: Chiang Mai Montessori International School (WASC-accredited) covers the early years, and Esara offers an integrated curriculum through high school. Together they provide a seamless Montessori-to-secondary path.

Annual tuition: Contact school
French curriculum
A French national curriculum taught in French and English, ages 2–12. The only French-curriculum school in the city — and it only covers primary, so plan for secondary elsewhere.
Annual tuition: ฿220,000–฿235,000 (~$6,500–$6,900)
Bilingual / Thai-English
Bilingual Thai-English with American curriculum elements and project-based learning. Considerably lower fees than the full international schools. Worth considering for younger children or longer-stay families who want their kids to develop genuine Thai language skills alongside English.

What does it actually cost?
Annual tuition at full international schools in Chiang Mai generally runs ฿280,000–฿900,000/year (~$8,200–$26,500). Bilingual schools and early-childhood programs can start considerably lower.
On top of tuition, budget for:
- One-time enrollment or registration fee: typically ฿50,000–฿200,000, paid once on entry
- School bus (if available): usually ฿30,000–฿60,000/year depending on route
- Uniform and supplies: ฿10,000–฿30,000/year
- Extracurriculars and field trips: varies widely
Here's the honest context: international schools aren't cheap in Chiang Mai. Compared to Bangkok's top schools — which can run ฿700,000–฿1,000,000+/year — you'll find real savings here, and next to international schools in Singapore or Shanghai, Chiang Mai can look like a bargain. But for many expat families, school fees are the single largest cost center in their Chiang Mai budget. Factor this in before you commit to a neighborhood and a lease.
How do you choose?
There's no single "best" international school in Chiang Mai — only the best fit for your child's learning style, your budget, and your long-term plans. A British family expecting to return to the UK may prioritise entirely different factors from a family planning to stay in Thailand long-term, or one seeking an IB pathway for global university options. The school that's right for your neighbor's kids may be entirely wrong for yours.
If you want to explore options in person, the Chiang Mai International School Education Fair is worth attending. It's an annual event where schools present directly and you can talk to admissions staff in one place — free entry for visitors.
For families who want to think through the decision before committing to a neighborhood and a lease, this is exactly the kind of thing we work through in a CNXlocal relocation consultation. Not to make the decision for you — to make sure you're asking the right questions first.

Questions to ask when visiting schools
Beyond the marketing brochure, here's what actually matters:
- What's the current waitlist situation for my child's year group?
- Does school bus service cover our neighborhood?
- What's the student-to-teacher ratio in my child's year group?
- How does the school handle mid-year enrollment — relevant if you're not arriving in August?
- What documentation is required for enrollment, and how does it interact with our visa type? Many families in Chiang Mai use an education visa — including the ED plus guardian visa — specifically tied to school enrollment. Our guide to long-term visas for expat families covers how this works.
- What happens to transcripts and academic records if we leave Thailand — are they issued in a format recognised by schools in your home country?
- For IB schools: which specific programs are authorised and currently running, not just planned?
Frequently asked questions
What is the best international school in Chiang Mai?
There isn't one — only the best fit for your family's curriculum needs, budget, location, and values. Factors like accreditation, class size, and the school's philosophical approach (faith-based, sustainability-focused, bilingual) matter as much as academic rankings.
How much do international schools in Chiang Mai actually cost?
Expect ฿280,000–฿900,000+/year in tuition for full international options, plus one-time registration fees of ฿50,000–฿200,000. Add school bus, uniforms, and extracurriculars on top. For most expat families, school fees are the single largest expense after rent — often larger.
Are there waitlists?
Yes, especially at popular schools and for popular year groups. Apply early and have backup options. Some schools fill particular year groups months before the school year starts.
Do schools offer bus service?
Most do, but coverage and cost vary — and not all moobans are covered. Always confirm the route directly with the school before you commit to a neighborhood.
Is an education visa easy to get through a school?
Yes — many families use the ED plus guardian visa tied to their child's enrollment. It's one of the most common long-stay visa strategies for expat families in Chiang Mai. See our guide to long-term visas for expat families for details.
Can we homeschool or worldschool instead?
Absolutely — and many expat families in Chiang Mai do exactly that, either full-time or in a hybrid with part-time enrollment. Our guide to homeschooling and worldschooling in Chiang Mai is coming soon.
How do Thai and international schools differ?
International schools follow foreign curricula in English with global accreditation, designed to translate across borders. Bilingual schools blend Thai national requirements with international elements at considerably lower cost — a solid option if you're planning a long stay and want your kids to develop Thai alongside English.
What about younger kids who aren't school-age yet?
Chiang Mai has solid options for pre-school-age children — from nannies to flexible daycares to preschools popular with expat families. Our guide to finding a nanny or daycare in Chiang Mai covers what's available, what it costs, and what to look for.
Fees and availability change annually. Always verify directly with schools before making decisions.
