TSI International School (TSI)
A British-curriculum school founded 1985 as Thai Sikh International School, now operating across the Bearing campus (ages 2–18) and the Wongwianyai primary campus. Around 400 pupils, IGCSE and A Level.
In brief
TSI International School has taught in Samut Prakan since 1985 and now takes around 400 pupils aged 2–18 along the British curriculum, through Cambridge IGCSE and on to A Level. It holds accreditation from the Council of International Schools, and in the 2023–24 IGCSE round the school posted 50 per cent of grades at A to A and 92 per cent at A to C. Graham Lonie joined in 2017 and stepped up to Head of School in 2025.
Parent reviews are consistently positive on value, with families describing reasonable fees, native English-speaking teachers, an international standard of education, and children who are happy to go to school. The small-school feel surfaces in both parent and staff comments, with small classes and a close community named as strengths. Staff opinion is more mixed. Some praise the compensation and class sizes; others criticise management and say teacher input should be handled better.
