Traill International School
School in Bangkok
Quick answer
Traill International School Bangkok serves 390 students from 30 nationalities aged 3 to 18. The school delivers the National Curriculum of England with IGCSE and A Level pathways, accredited by BSO, FOBISIA and CIE. Tuition $11,000-$17,000 per year — strong value for a multi-accredited British international school. Strong fit for British and Thai-British expat families on Bangkok assignments seeking British-track education with intentionally smaller cohort sizes than the larger Bangkok internationals (NIST, Patana, Harrow).
