SISB's Nonthaburi campus runs a continuous pathway from Nursery at age two to Sixth Form at eighteen, at 98 Moo 4, Khlong Phra Udom in Pak Kret district. The early years blend the UK Early Years Foundation Stage with the Singapore curriculum and build English, Chinese and Thai in parallel; primary follows the Singapore curriculum proper; secondary runs a hybrid Singapore-Cambridge programme that converges on the full Cambridge IGCSE in Grades 9 and 10; and the Sixth Form teaches Cambridge International AS and A Level. SISB is part of a SET-listed group operating six campuses in Thailand, which gives the school a scale and a governance structure that independent single-site schools do not have. It was named on our Nonthaburi schools hub for months without an address or a profile page; this entry corrects that.
Also known as: Singapore International School of Bangkok, Nonthaburi campus
Where this school stops
Nonthaburi’s eight schools end at four different ages, so this is the first question to settle — not the last. “Runs to 18” and “has a sixth form on this campus” are separate claims.
Sixth Form at 18, taught on campus
Where the campus actually is
98 Moo 4, Khlong Phra Udom, Pak Kret District, Nonthaburi 11120
Reached by road in western Pak Kret. Admissions and general enquiries both run through +66 2502 9898.
Is it on a rail line?
Partly. The campus is in Pak Kret district, which the Pink Line monorail now serves along the Chaeng Watthana corridor, but Khlong Phra Udom sits west of that corridor and no station is adjacent. Treat this as a car or school-bus run with rail as a fallback for older students rather than a rail-first school.

The curriculum pathway, stage by stage
- Nursery-Kindergarten (2-6) -- a blend of the UK Early Years Foundation Stage and the Singapore curriculum, building English, Chinese and Thai
- Primary (6-12) -- the Singapore curriculum, with English, Maths, Science and Chinese as core
- Secondary (12-16) -- a hybrid Singapore and Cambridge programme across 11 core subjects, moving to the full Cambridge IGCSE curriculum in Grades 9 and 10, with up to 9 subject choices
- Sixth Form (16-18) -- Cambridge International AS and A Level
Accreditations & authorisations
Worth separating: an examination-board authorisation (Cambridge, IB, College Board) means a school may enter pupils for those exams. A whole-school accreditation (WASC, CIS, COBIS, Cognia, ISQM) assesses the school itself. Both matter; they are not the same claim.
- Cambridge International -- IGCSE and AS/A Level pathways
- Part of SISB Public Company Limited, listed on the Stock Exchange of Thailand
Religious character
None published. SISB advertises no religious character or requirement.
Boarding
Day school. This is the clearest boarding trap in the province: SISB as a GROUP does run boarding, but only at its Pracha Uthit campus in Bangkok. The Nonthaburi campus has none. A directory entry reading "SISB: boarding yes" is describing a different campus roughly 30km away.
Who it suits
Families who want the Singapore curriculum's well-known rigour in maths and science through primary, with a recognised Cambridge exit at IGCSE and A Level; families who value Chinese taught seriously from nursery alongside English and Thai; and families who want a large-group school with a corporate parent rather than an independent single-site school.
What we could not verify — and where sources disagree
We publish these openly rather than smoothing them over. A school guide that hides its uncertainty is not much use to a family making a decision this big.
- Our own hub previously gave this school's area as simply "Nonthaburi" and placed it as the closest campus to Bang Yai and Central Westgate. It is in PAK KRET district, at Khlong Phra Udom -- a different part of the province entirely. That error has been corrected.
- No whole-school accreditation could be verified for the Nonthaburi campus specifically beyond its Cambridge pathway authorisations and its parent company's listing. Cambridge authorisation means the school may enter pupils for those exams; it is not the same as a CIS, COBIS or WASC whole-school accreditation. Ask what the campus itself holds.
- The head of school is named on the campus page as Kelvin Koh. Leadership changes often and is worth re-checking at the point of enquiry.
Ask every Nonthaburi school this
- Does the school actually go as far as your child needs? Two of the eight -- St. Andrews Samakee (14) and MYIS (16 for now) -- stop before the end of secondary, so you will be choosing a second school. Ask before you enrol, not in Year 8.
- Which rail line, if any, is genuinely usable for your household? Nonthaburi has the Purple and Pink lines, but no campus here is a station-to-gate walk. Establish whether you are a rail family with a feeder leg, or a car family who happens to live near a station.
- What does the school bus actually cover, and is your address inside the catchment? In a province split by the Chao Phraya and by two motorway corridors, the bus map decides which neighbourhoods are realistic far more than the distance on a map does.
- Drive the run at 07:00 on a weekday before you sign a lease. Chaeng Watthana, Ratchaphruek and Tiwanon at rush hour bear no relation to the same roads at midday.
- Is the accreditation whole-school, or is it an examination-board authorisation? Cambridge, IB and College Board authorisations say a school may run those exams. WASC, CIS, COBIS, Cognia and ISQM assess the whole school. Both matter, and they are not the same claim.
- If faith matters to you in either direction, ask directly. Two of the eight schools are explicitly Christian -- one Catholic, one Bible-based and ACSI-affiliated -- and the other six publish no religious character at all.
- Ask what the year group's actual size is this year, not the school's total roll. Several of these schools are small by design, which many families want -- but you should know the number before you decide, not after.
BAANLYY does not rank, endorse or accept payment from schools. Facts on this page are compiled from SISB Nonthaburi Campus's own published material and independent cross-checks, and we deliberately publish no per-school fee figures — they change annually and a stale number is worse than none. Always confirm current admissions, fees, year groups, accreditation status and campus details directly with the school. Visit the official SISB Nonthaburi Campus page →

Nonthaburi has two MRT lines but no campus at a station gate — the neighbourhood you choose is still the commute. Compare all eight schools first, then match an area.
