IB Curriculum International Schools in Chiang Mai, Thailand

About international schools in Chiang Mai, Thailand

IB international schools in Chiang Mai form a small, tightly knit sector where individual schools may offer a single IB programme or several stages of the IB continuum, so you should check each school’s authorised programmes before applying. Instruction is usually in English, though a number of schools run bilingual Thai - English pathways and teach Thai language and culture as part of the curriculum. Annual tuition for IB places commonly falls in the mid-hundreds of thousands of Thai baht, with lower and higher outliers depending on age, boarding and school facilities; families should also budget for enrolment, transport, meals and activity charges. Admissions generally follow the international school calendar with a main intake in August, but many schools publish their own term dates and offer rolling or additional intakes, so start enquiries several months before you plan to move.

FAQs for Thailand

Which IB programmes are available in Chiang Mai and what ages do they cover?
The IB offers four programmes: the Primary Years Programme (PYP) for early years and primary, the Middle Years Programme (MYP) for lower secondary, the Diploma Programme (DP) for the final two years of secondary, and the Career-related Programme (CP) for vocationally oriented upper secondary students. Not every Chiang Mai school runs every programme, so confirm which specific programmes a school is authorised to deliver before assuming a continuous IB path.
How much do IB international schools in Chiang Mai typically cost and what extra fees should I expect?
Published tuition figures vary by school and year group, but many international schools in Chiang Mai show annual fees in the mid-hundreds of thousands of baht; a few schools and senior year groups attract noticeably higher fees, and boarding adds further cost. On top of headline tuition expect one-off enrolment or capital fees, plus recurring extras such as school transport, meals, uniforms, learning materials and extracurricular activities - it is common advice to budget an additional 10 - 20% above published tuition to cover these extras.
When should we start the application process and what does it involve?
Begin enquiries and the application process at least three to six months before your intended start date, and earlier for popular year groups such as entry to Year 10 or Year 12; many schools publish a main intake in August but also run separate intakes or rolling admissions. Typical admissions steps include submission of previous school records, an application or registration form, interviews or assessments (academic and English), and provision of medical and immunisation records - check each school’s published admissions checklist and term dates.
What language support and Thai requirements should we expect?
English is the primary language of instruction at Chiang Mai’s IB schools, but several schools operate bilingual models with substantial Thai language teaching and cultural education built into the timetable. Thai national regulations and school policy can affect how Thai language and national subjects are delivered (especially for Thai nationals), and most international schools also offer additional English-language support for students joining from other systems.
What should a relocating family look for when comparing IB schools in Chiang Mai?
Compare which IB programmes are authorised, the strength of English-language and learning-support provision, class sizes, pastoral care and university-guidance services, and the school’s published exam and assessment approaches. Also weigh practical factors such as campus location relative to your home and Chiang Mai’s seasonal air-quality issues, transport options, boarding availability (if relevant) and the full cost of attendance including extras.
