Anglo Singapore International School

Anglo Singapore International School was founded in 2003 with four students in a small building at the end of Sukhumvit Soi 31. Its original aim was to give Singaporean families abroad the same academic standards as in Singapore and the UK. The main Bangkok campus opened in 2012 at Sukhumvit Soi 64, near Punnawithi BTS in Phra Khanong, and runs from kindergarten to Junior College (Year 12/13). The Sukhumvit 31 campus in Watthana now teaches kindergarten and primary only, with older students moving to Sukhumvit 64. A third campus in Nakhon Ratchasima opened in 2014. Across all three campuses there are about 1,800 students from more than 25 nationalities, many of them Thai and other Asian families.

The curriculum combines Singapore-style mathematics and science with the Cambridge International framework. Primary runs for six years (P1 to P6). Lower secondary (Years 7 and 8) leads to Cambridge IGCSE examinations at the end of Year 10. Junior College students then choose between Cambridge International A Levels, a Pearson BTEC International Level 3 Extended Diploma (introduced in 2025–26 in Art & Design and IT) or the school's own high school diploma. Mother-tongue classes are offered in Mandarin, Japanese and Korean, alongside Thai. The school is accredited by CIS and WASC and is a Cambridge and Pearson exam centre. Scholarships are available at Junior College level for academics, debate and sport.

The Sukhumvit 64 campus is purpose-built. It has biology, chemistry and physics labs, a 25m pool and a learner pool, FIBA-standard basketball courts, badminton courts, a five-a-side football pitch, an auditorium, music and art rooms, libraries, a greenhouse and a planted central courtyard. Classrooms have air purifiers. Tuition includes textbooks, stationery, snacks, lunch and school outings. Annual fees at Sukhumvit 64 run from about THB 398,000 in K1 to THB 523,000 in P1–P2, THB 678,600 in Years 7–8 and THB 765,000 in Years 9–10.
