Singapore International School Bangkok, almost always shortened to SISB, is a Singapore curriculum school group that opened its first Bangkok campus at Ekkamai in 2001 and now operates several sites across the city and beyond. It teaches in English with a trilingual emphasis on English, Chinese and Thai, and it appears among the city's international options on our Bangkok city hub. The draw for many families is the Singapore approach to mathematics and science, layered with Cambridge and International Baccalaureate qualifications at the senior end.

At a glance
Curriculum and academics
SISB builds its teaching on the Singapore curriculum, well known for its structured mathematics and strong science, and overlays internationally recognised qualifications as students move up. Senior students typically follow Cambridge IGCSE and then either Cambridge A Levels or the IB Diploma at the campuses that offer it, giving two clear routes into university worldwide. English is the language of instruction throughout, with Chinese and Thai taught as part of the trilingual model.
That mix suits families who value the discipline of the Singapore method but want a globally portable exit qualification. If you are comparing the IB Diploma with A Levels and the American route before deciding, our IB curriculum guide explains how the Diploma is structured and who tends to thrive on it.

Singapore International School Bangkok fees
SISB sits in the mid band on our Bangkok international school fees guide, generally more accessible than the established British and American flagships while still delivering recognised international qualifications. Fees vary by campus and rise with each stage, so treat any single figure as indicative and confirm the current schedule with the campus you are applying to.
Budget for the standard Bangkok extras alongside tuition: a registration fee, a deposit, uniform, examination entry in the IGCSE, A Level or IB years and an optional bus service. Our fee calculator helps turn the headline tuition into a realistic annual total once those line items are included.
Admissions
The academic year starts in August, so the main application window runs through the preceding autumn and winter, though SISB campuses do admit through the year where space allows. Assessment is age appropriate and usually includes English and mathematics checks, with previous school reports taken into account and additional language placement for the Chinese and Thai programmes.
Because the group runs multiple campuses, availability differs from one site to another, so it is worth enquiring about more than one if your preferred location is full. The practical first steps are to contact the campus admissions team, share recent reports and arrange a visit.
Location and who goes there
SISB's campuses are spread across Bangkok and the surrounding province, from the original Ekkamai site to Pracha Uthit, the Suvarnabhumi campus near the airport at Bang Phli and Thonburi on the west bank, which gives families a choice of commute depending on where they live. Several campuses sit close to expressway access rather than a single rail line, so transport planning matters when you shortlist a site.
The community is international with a notable East Asian presence reflecting the Singapore and Chinese language focus, alongside Thai and wider expatriate families. For the bigger picture of Bangkok neighbourhoods and the schools near each one, head back to the Bangkok city hub.
