About international schools in Chiang Mai, Thailand

Chiang Mai’s international schools combine a surprisingly wide mix of programmes for a midsize city: you will find International Baccalaureate programmes, British (IGCSE/A-level) and American pathways, Montessori and bilingual Thai - English options, plus a small number of specialist curricula such as German and Singaporean models. English is the primary language of instruction at most schools, with Thai taught as a compulsory or strong second language and Chinese or Japanese commonly offered as additional languages. Annual tuition varies a lot by age and type of school - fees can start at roughly ฿100,000 a year at more affordable bilingual providers and commonly sit in the ฿300,000 - ฿500,000 band, rising higher for senior years or boarding places - and nearly all schools add one-off registration, development and optional extras (meals, transport, EAL support). Most international schools in Chiang Mai run a northern-hemisphere academic year with the main intake for the August term and an admissions cycle families should start preparing for several months in advance.

FAQs for Thailand

Which curricula and ages are offered in Chiang Mai’s international schools?
Chiang Mai schools cover the full age range from early years through to pre-university, and the city hosts IB Primary/Middle/Diploma programmes, British curricula (including IGCSE/A-Level), American-style programmes, Montessori early years and Thai-English bilingual models. Some schools also follow German, Singaporean or trilingual models for specific year groups, so check each school’s published programme and the age ranges they serve.
How much should we budget for tuition and extra costs?
Tuition varies by school and year group: at the low end bilingual providers commonly start around ฿100,000 a year, many full international schools sit in the ฿300,000 - ฿500,000 band, and senior-year or boarding places can be substantially higher. In addition to published tuition expect one-off application/registration or enrolment fees, annual development/building fees, and optional costs such as uniforms, meals, school bus, exams and EAL or specialist support.
When should we apply and how does the admissions rhythm work?
Most international schools in Chiang Mai operate a northern-hemisphere academic year (roughly August - June) with the main intake at the start of the August term; many schools open applications several months earlier so families commonly begin enquiries in November - February for the following August. Mid-year starts are possible at some schools but places can be limited, and the process usually involves an application form, previous school reports, age-standardised placement assessments or interviews and a non-refundable application or registration fee.
What languages are used and what support is available for children who don’t speak English?
English is the principal language of instruction in nearly all international schools, while Thai language and culture lessons are typically part of the curriculum and some schools offer structured Chinese or Japanese classes. Many schools provide English as an Additional Language (EAL) or learning-support programmes for newcomers and will assess language needs during admissions to recommend appropriate support or a phased entry.
What practical checks should we make when shortlisting schools in Chiang Mai?
When visiting, check that the school’s stated curriculum and accreditation match your expectations, ask about class sizes and teacher turnover, review safeguarding and pastoral care arrangements, and confirm transport routes, extra costs and the school calendar so it aligns with family plans. Also request recent sample reports or assessment information, speak to current parents if possible, and confirm how the school handles transitions and language support for mobile expat families.
