* Years marked with an asterisk are based on market research and not directly from the school, so please reference with care.

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).
