International Schools in Thailand

International schools in Thailand are a diverse sector that largely serves expatriate families and Thai families seeking an English-medium education; most offer internationally recognised programmes such as the British (IGCSE/A-Levels), American (US high-school/AP), the International Baccalaureate (IB) and a growing number of Singaporean or bilingual tracks. English is the primary language of instruction at the majority of these schools, while Thai language and culture lessons are required for Thai students and are commonly offered to international pupils; many schools also run Mandarin and other modern-language options. Fee levels vary widely by city and school type but typical annual tuition in Bangkok ranges from the mid-hundreds of thousands of baht to over a million baht once one-off development charges and extras are included, so budgeting beyond headline tuition is important. Admissions are generally busiest around the main academic intake (many international schools follow an August/September start with alternative mid-year intake points), but places, assessments and waiting lists mean families commonly apply well in advance and monitor rolling availability.
