About international schools in Chiang Mai, Thailand

American-curriculum international schools in Chiang Mai broadly deliver a US-style programme - often a K - 12 pathway leading to an American high-school diploma with Advanced Placement (AP) options at the upper levels - delivered in English but adapted for local students and regulations. English is the language of instruction while Thai language and culture classes are typically part of the timetable; many schools also offer Mandarin or other modern languages as additional options. Tuition varies by school size and facilities, but full-service K - 12 international schools in Chiang Mai commonly charge in the mid-hundreds of thousands of Thai baht per year (with smaller bilingual or specialised providers charging noticeably less). Schools generally follow an international calendar with a main intake in August (and a January semester start at many institutions), and families should expect assessments, English-proficiency checks and to apply several months before the desired start date to secure places.

FAQs for Thailand

What does an "American curriculum" school in Chiang Mai typically teach and what qualification will my child get?
An American-curriculum school in Chiang Mai will normally follow US-style grade levels, core subjects aligned with common US standards, and college-preparatory options such as Advanced Placement (AP) courses in upper secondary. Graduating students usually receive an American high-school diploma; some schools complement that with AP exam preparation or recognised international accreditation.
Which languages are used at these schools and what language support is available?
English is the primary language of instruction at American-curriculum schools, while Thai language and culture lessons are commonly included for all students. Many schools offer additional modern languages such as Mandarin (and occasionally Korean or French), and most provide English as an additional language (EAL/ESL) support or entry assessments for non-native English speakers.
How much should I expect to pay for tuition and what other fees are common?
Tuition for full K - 12 international schools in Chiang Mai commonly sits in the mid-hundreds of thousands of Thai baht per year, though exact amounts vary by school, grade level and included services. On top of annual tuition families should budget for one-off registration or capital levies, activity and exam fees, uniforms, transport and optional services such as after-school care or school meals.
When should we apply and how do admissions typically work?
Most American-curriculum schools in Chiang Mai operate two main semesters with Semester 1 beginning in August and Semester 2 in January, and many accept enquiries and applications year-round for spaces that arise. Admissions commonly include an inquiry form, a school visit or interview, age-appropriate assessments and English-proficiency checks, so families should start the process several months before the intended start date to allow time for assessments and paperwork.
What should parents look for when comparing American-curriculum schools in Chiang Mai?
Look for clear information on the curriculum outcomes (diploma, AP availability), accreditation or external evaluation, typical class sizes and the English-language support offered to non-native speakers. Also check practical matters such as the school calendar, bus routes and after-school provision, published fee schedules and the admissions process timeline so you can compare total cost and fit for your child’s age and needs.
