Singapore International School of Bangkok

SISB Pracha Uthit is the flagship campus of SISB, the only education group listed on the Stock Exchange of Thailand, which gives the network a level of public financial transparency and scale that most privately held international school groups in Bangkok do not have.

Founded in 2001, this campus teaches a combined Singapore and UK curriculum trilingually in English, Chinese, and Thai, a genuinely three-language academic structure that goes beyond the bilingual or English-medium-with-language-classes approach most other Bangkok schools use.

As the flagship of a six-campus national network, Pracha Uthit benefits from shared curriculum resources and institutional scale across SISB's other Thai locations, while still operating with its own local admissions and campus culture.

Families specifically interested in a genuinely trilingual Singapore-curriculum education, rather than a British or American framework, are the core audience for SISB, distinguishing it clearly from the broader Bangkok international school market.
