SISB International School (Nonthaburi Campus)

SISB Nonthaburi opened in August 2023 as the fifth campus of the SISB group, which started the Singapore International School of Bangkok in 2001. It sits on an 18.5-rai site in Khlong Phra Udom, Pak Kret district, north-west of Bangkok, and cost around THB 700 million to build. The campus is planned for Nursery through Grade 12 and is growing year by year; for 2026–2027 it is admitting students up to Grade 11. It is a day school; boarding within the group is offered at the Pracha Uthit campus in Bangkok.

Each stage follows a different curriculum. Nursery and Kindergarten use the UK Early Years Foundation Stage, combined with Singapore content and daily English, Chinese and Thai. Primary follows the Singapore curriculum, known for its approach to maths and science. Grades 7 and 8 use a hybrid of Singapore and UK programmes, Grades 9 and 10 lead to Cambridge IGCSE, and Grades 11 and 12 study Cambridge International AS and A Levels. English is the main language of teaching, and Chinese and Thai are taught throughout.

The campus is built around a red-brick main block and has an indoor swimming pool, a sports hall with spectator seating, a full-size artificial football pitch, an auditorium, a library, science and music rooms, a large canteen and shaded playgrounds. For 2026–2027, annual tuition is THB 401,700 for Nursery, THB 470,700 for Primary 1–2, THB 567,300 for Primary 5–6, THB 609,300 for Grades 7–8, THB 650,700 for Grades 9–10 and THB 789,300 for Grade 11. Families also pay education resources and meal fees and a one-off enrolment fee of THB 220,000, which is currently being discounted.
