Thailand has long been a favoured destination for expatriate families, and its international school sector has grown substantially to match demand. Bangkok is the primary hub, home to over 60 international schools, with notable institutions in Phuket, Chiang Mai, and Pattaya serving resort and retirement communities.

The Bangkok international school landscape ranges from small boutique schools to large campus institutions like Bangkok Patana, NIST International School, and International School Bangkok (ISB) — all achieving strong IB Diploma results year after year. Annual fees in Bangkok typically run from THB 300,000 to THB 900,000, lower than Singapore but on par with Kuala Lumpur's premium schools.

Thailand's straightforward visa processes, year-round warm climate, and vibrant expat community make it an attractive long-term base for international families from Australia, Europe, North America, and across Asia.
