Lanna International School Thailand

Chiang Mai's oldest British school, established 1993. Cambridge curriculum, ages 2–18, IGCSE and A-Levels. A FOBISIA member — the only school in northern Thailand with that accreditation. A diverse student body across 40+ nationalities, with a consistent record of top-100 university admissions. It draws some of the warmest word-of-mouth of any school in the city — parents single out the newer primary campus, the teaching community, the language options, and a secondary strong across academics, sports, and the arts. The early years in particular get high marks, and students are known to keep to English between classes.
