Market research: 2022-23, Chiang Mai Family Guide 2022/23 school directory ↗ · 2023-24, BKK Kids 2024 International Schools Guide ↗ · 2025-26, CMIS 2025/26 tuition breakdown (FlipHTML5), from editor research. These list tuition by school level; we spread them across today’s year groups and add this year’s compulsory charges to make an all-in figure. Estimates fill years with no figure: between two known years we assume steady growth; before the earliest known year we work back at the school’s own rate, or 5.8% a year (the median rise across Chiang Mai schools that publish older schedules). A paler top on a column marks a range (charges that vary by grade).
