American Pacific International School
Chiang Mai's first internationally accredited boarding school, offering IB PYP, MYP and Diploma across two campuses - a city Primary Campus for Nursery to Grade 5 and a residential Main Campus in the Samoeng hills for Grades 5-12. 2025-2026 day…
In brief
Chiang Mai's first internationally accredited boarding school, founded in 1997 and now a full IB continuum (PYP, MYP, DP) running from pre-nursery through Grade 12 across two campuses in Hang Dong and Mae Hia.
Around 400 students from over 20 nationalities, WASC accredited, with a rural main campus surrounded by rice fields and small villages on the road to Samoeng. Four boarding houses and a residential programme that, unusually, accepts boarders from age six. That early-boarding option is the school's distinctive feature in the Chiang Mai market and is what attracts the regional Asian families who make up a meaningful share of the roll.
Families consistently praise the staff warmth, the international mix and the rural setting. The IB delivery is the academic backbone for those targeting English-language universities. Practical considerations are the commute from central Chiang Mai to the main campus and the fee step-up against the bilingual schools in town, with day fees running roughly THB 230,000 to 500,000 depending on grade.

Reviews
- Boarding and day school 45 minutes outside Chiang Mai. Reddit teacher reviews paint a school known more for setting and lifestyle than academic firepower.
- Former staff describe an isolated rural campus where first-year teachers must live on site, share meals with students, and struggle to switch off. One ex-teacher: "You're always around students, for every meal, so it can feel like you're always working."
- Same teacher said the head of school has been in post 10+ years with the owners' backing, while other admin roles have churned more often.
- Teachers flag low pay relative to other international schools, with starting salaries that one applicant put around USD 21,000 for four years' experience. Posters describe it as a stepping-stone first international post rather than a destination school.
- For-profit ownership shows in the facilities. One former teacher: "facilities are old and unlikely to be updated."
- Reports of staff at the dorms and nearby bars informally feeding information back to the owners, which posters describe as uncomfortable.
- Big draws are Chiang Mai itself, the rural campus, IB continuum across PYP, MYP and DP, and the chance to break into international teaching.
