Choosing an
International School
in Thailand
Choosing a school is usually the single decision that shapes everything else about moving to Thailand — where you live, how your child settles in, and how connected your family feels to the country. This guide walks through the factors that actually matter, in the order most families find useful, so a tour or an open day becomes a conversation rather than a guessing game.
Home second.
Don't choose the brochure.
Choose the fit.
International schools can look remarkably similar online. The useful differences only appear when you start asking how a school fits your child, your commute and the life you are actually building in Thailand.
Use these eight questions as your shortlist. They turn a school tour from a sales presentation into a proper comparison.
Curriculum
Where might your child study next?
Accreditation
Who independently checks the school?
Location
What does the school run do to family life?
Class size
How much individual attention is realistic?
Language
What support exists beyond conversation?
Facilities
Will your child actually use them?
Admissions
Can you get the place you need, when you need it?
Fit
Does your child feel they belong?
Start with curriculum, because it shapes everything else
The curriculum a school follows determines its calendar, its exam structure, how progress is measured, and often the university pathways it naturally leads to. Thailand’s international schools mostly cluster around British, American, International Baccalaureate (IB), and a handful of other national curricula such as Singapore or Australian systems.
This guide focuses on how to weigh a school overall. For a full breakdown of what each curriculum actually involves day to day — qualifications, exam boards, and how well they transfer if you move country again — see our companion guide, International School Curricula in Thailand Explained.

Check what accreditation actually tells you
Accreditation is an external body’s independent check that a school meets a recognised standard of teaching, safeguarding, and governance — it is not the same as a curriculum, and a school can follow the British curriculum without holding any external accreditation at all.
The bodies most commonly seen among established international schools in Thailand include the Council of International Schools (CIS), the Western Association of Schools and Colleges (WASC), the New England Association of Schools and Colleges (NEASC), and curriculum-specific bodies such as the International Baccalaureate Organisation for IB schools or Cambridge International for British-curriculum schools sitting IGCSEs and A-Levels.
Accreditation is worth asking about directly rather than assuming: request the name of the accrediting body and roughly when the school was last reviewed, since accreditation is typically renewed on a cycle rather than granted once and forgotten.
Location decides your daily life more than most parents expect
In Bangkok specifically, traffic makes the difference between a school ten kilometres away and one three kilometres away far larger than the map suggests — a longer commute eats into homework time, after-school activities, and a young child’s energy for the school day itself.
Outside Bangkok, in cities such as Phuket, Chiang Mai, Pattaya, and Hua Hin, the international school options are fewer but generally more spread out geographically, so the location question is often less about traffic and more about which side of the city you end up choosing to live on.
A practical approach: shortlist schools first, then actually drive the commute at drop-off and pick-up time before signing anything, since a school website's stated “15 minutes from Sukhumvit” rarely accounts for rush hour.
Class size and the questions worth asking about it
Published class-size figures are a starting point, not the full picture — the more useful questions are about the adult-to-child ratio in early years specifically, whether classes are streamed by ability in core subjects, and how learning support is resourced when a class has a wide range of ability within it.
Smaller schools often mean smaller classes but also a narrower range of subject choices at secondary level, particularly for IB Diploma or A-Level subject combinations — worth checking directly if your child already has a strong academic direction in mind.
05 · LANGUAGE SUPPORTLanguage support matters more than families often plan for
Even in a fully English-medium school, children arriving with limited English typically need structured English as an Additional Language (EAL) support to keep pace with content subjects, not just conversational English lessons on the side.
Ask specifically how EAL support is delivered — withdrawal from mainstream classes, in-class support alongside the regular teacher, or a separate intensive programme before mainstream entry — since schools vary significantly here, and the answer affects how quickly a child settles academically rather than just socially.
For non-native English speaking families, and for families considering a bilingual or Thai school as an alternative, our comparison guide International vs Bilingual vs Thai Schools: What's the Difference? sets out the trade-offs in more depth.
Facilities: judge them against how your child actually spends their week
Glossy facilities photography is the easiest thing for a school to get right and the least useful thing to judge a school by. A better filter: ask how often the facilities you're shown are actually used by students in your child's specific year group, rather than how impressive they look on an open day.
A small number of Thailand’s international schools also offer boarding alongside day places — useful to know even if boarding isn’t your immediate plan, since boarding schools often run a noticeably fuller extracurricular and weekend programme even for day students, given the infrastructure already exists on site.
Admissions: the short version
Admissions processes vary by school but generally involve an application, an assessment appropriate to the child's age, a review of previous school reports, and — particularly at popular Bangkok schools — a waiting list for certain year groups. Some schools accept mid-year entry more readily than others.
This is covered in full in International School Admissions in Thailand, including realistic timelines for when to start the process before the academic year you're targeting.

Fit is real, even though it’s the hardest thing to measure
Two schools can look nearly identical on paper — similar curriculum, similar fees, similar facilities — and still feel completely different to actually spend a day inside. Pace, discipline style, how much value is placed on competitive achievement versus collaborative learning, and the makeup of the existing parent community all shape whether a school genuinely suits your child.
This is the strongest argument for visiting in person rather than deciding from a website alone, ideally on an ordinary school day rather than a staged open day, and ideally with your child present if they're old enough to have and express an opinion.
Questions worth asking on a school tour
Seven questions that cut through the polished tour and help you compare schools on the things that matter.
- 01
Which body accredits the school, and when was the last review?
- 02
What is the actual adult-to-child ratio in the year group my child would join?
- 03
How is EAL or additional language support delivered, and by whom?
- 04
What happens if my child needs to join mid-year rather than in August?
- 05
How many students in the senior years came up through the school versus joined recently?
- 06
What is the school's policy on discipline, and how are disagreements between parents and the school usually resolved?
- 07
Can I speak to a current parent who isn't arranged by the school's admissions office?

Choosing an international school in Thailand: FAQs
Quick answers, with links to the full guides.
How do I choose an international school in Thailand?
Start with where your child is likely to study next, then check accreditation, the daily commute, class sizes, language support and how the school feels on an ordinary day. Visit before you decide, and compare at least three schools on the same questions.
What should I ask on a school tour?
Ask who accredits the school, the real adult-to-child ratio in your child's year group, how English support works, what happens with mid-year entry, and whether you can speak to a parent the admissions office hasn't arranged.
What accreditation should an international school in Thailand have?
Schools are licensed by the Office of the Private Education Commission, and schools teaching a foreign curriculum must join a recognised accreditation body such as CIS, WASC, NEASC, Cognia or COBIS within a year of opening. Ask which body accredits the school and when it was last reviewed.
Which curriculum should I choose?
The one your child can continue wherever you are likely to live next. See international school curricula explained.
Should we choose a school or a home first?
The school. Then look for a home within a manageable commute — in Bangkok, drive the route at school-run time before you sign a lease.
What if my child doesn't speak English well?
Ask how English as an Additional Language support is delivered, by whom, and for how long. Some families also consider bilingual schools — see international vs bilingual vs Thai schools.
When should we start looking for a school?
Ideally nine to twelve months before your child starts, especially for popular Bangkok schools. See our admissions guide.
How much do international schools in Thailand cost?
Fees vary widely by school, city and year group, plus application, registration and deposit charges. See international school fees explained.

What will university actually cost your child?
Many expat families in Thailand plan to send their children to university in the UK, USA or Australia. These are consistently ranked among the best in the world -- but the true cost, tuition plus living expenses, is significant and rising every year.
United Kingdom
£27,000 – £55,000per year
Tuition + living costs, most 3-year degrees
United States
$32,000 – $60,000per year
Tuition + living costs, most 4-year degrees
Australia
AUD 45,000 – 85,000per year
Tuition + living costs, most 3-4 year degrees
Figures are approximate 2026 ranges based on published international student tuition and living-cost data. Actual costs vary by institution, course and city -- treat these as planning estimates, not quotes.
The earlier you start, the less it costs you
A university education 10-15 years from now will cost considerably more than these figures, not less. The single biggest lever available to parents isn't finding extra money later -- it's giving compound growth more time to work. Starting a structured education fund while a child is young, even with modest contributions, can cover a meaningfully larger share of the eventual bill than starting the same plan five or ten years later.
Plan ahead, and reduce the pressure later
Lawrence Young, Just Landed in Thailand's education fee planning partner at SVN Capital, helps expat families in Thailand build a realistic plan for future university costs -- and how it connects to your wider retirement and financial planning too.
