One of the newer American-curriculum options in Chiang Mai, sitting in Saraphi off the Lampang highway and part of the local Ambassador Education Group. Common Core through Grade 12 with AP in the high school, WASC accredited through 2029. Families coming through tend to be warm on the teachers and the modern facilities; the harder edges concern teacher turnover, communication between school offices, and the heavily Asian (and large Chinese) intake that shapes the social mix.

Positives

  • Facilities and campus. Purpose-built since 2017 with separate buildings by age, science and computer labs, a fitness centre, courts and pool. Families consistently call it modern and well-kept.
  • Teachers and TAs. The day-to-day frontline staff get warm reviews. Teachers and teaching assistants come through as friendly, attentive, and engaged with the kids.
  • American pathway and AP. Common Core PreK-12 with AP in Grades 9-12, aimed at US and international university entry. WASC accreditation runs to June 2029.
  • Group and ownership. Part of the Ambassador Education Group, a Chiang Mai family education business with roughly three decades of local school operation behind it.

Considerations

  • Teacher turnover. Parents flag teaching staff changing often, and at least one case of a teacher dropping out mid-semester without explanation during the online-learning period.
  • Communication and administration. Communication between divisions and out to families gets criticised. Notices land with errors and recycled detail; the right office is not always easy to reach.
  • For-profit feel. A recurring teacher-side complaint is that decisions track revenue more than classroom quality. Parents echo this around deposits and fee handling.
  • Intake mix. Around thirty nationalities on paper, but the day-to-day room skews heavily Asian with a large Chinese cohort. English-language immersion looks different here than at the older Chiang Mai internationals.
  • Location. Saraphi campus sits directly off the Chiang Mai-Lampang superhighway. Easy to reach by car from the south and east of the city, less benign on foot or by bike, and the highway drop-off is a recurring grumble.
