International schools in Samut Prakan.

The short version

Samut Prakan is not a thin school market. It has ten international schools, spread across two clusters that have almost nothing to do with each other: a dense belt along Bangna-Trad in Bang Phli running from kilometre 7 out past kilometre 15 towards Suvarnabhumi, and a separate, rail-served group at Samrong and along Srinakarin in Mueang Samut Prakan. Between them the province offers the full IB continuum, three IB Diploma routes, two American diploma routes, two British A Level routes, the Singapore curriculum, daily compulsory Mandarin, Panjabi and Hindi at IGCSE, and the only confessionally Christian school in our Thailand coverage outside the mission-founded schools of the north-east. What it does not offer is a stable picture: this is the one province where a school families were shortlisting has closed, and where a well-known school has changed its leaving qualification without the directories catching up. Below: every school, where each stops, what a leaver holds, who is actually accredited, and which listings to distrust. For day-to-day budgeting pair this with the Samut Prakan cost-of-living guide, and use the where-to-live guide to match a neighbourhood to your school.

One school on most shortlists no longer exists

VERSO International School closed on 31 July 2026. It operated from 2020 on a 168-rai campus at Bang Chalong near Suvarnabhumi, and its own website now carries a closure announcement. BTS Group elected to close it after five years and handed the site to Wycombe Abbey; Wycombe Abbey International School Bangkok opened on the same campus in August 2026 as a British school with boarding houses. Third-party directories still list VERSO as a live, enrolling school with a student roll and accreditations attached, and AI-generated school round-ups repeat those listings. If you are working from a shortlist compiled before this summer, rebuild it.

The same instability shows up in smaller ways across the province, which is why every profile page here carries a “what has changed recently” section. Raffles American School has moved its senior years from Advanced Placement to the IB Diploma. D-PREP stopped being a primary school when its secondary campus opened in 2024. Thai-Chinese is mid-IB-candidacy. TSI is mid-rename and mid-accreditation at the same time. Every one of those changes post-dates the descriptions still circulating in directories.

All ten schools

Every international school whose campus is physically in Samut Prakan province. This is a starting point, not a ranking. Note how many are in Bang Phli district — and note that all of them are routinely filed under Bangkok.

Where each school stops — and what a leaver holds

Two separate questions, and this province separates them further than most. SISB Suvarnabhumi stops at Primary 6, around age eleven or twelve, and awards nothing — while being marketed across the Bang Kaeo property corridor as an international school. And a curriculum label is not a qualification: D-PREP runs an American programme to Grade 12 and names no leaving qualification anywhere on its site, offering Advanced Placement subjects for college credit instead, which is a different thing. For a family that may move country again, this table is the decision.

Accredited, authorised, or neither

These are three different claims and schools blur them constantly. A whole-school accreditation — WASC, CIS, NEASC, Cognia, ISQM — means an outside body has assessed the school itself. An examination-board authorisation — IB, Cambridge, College Board — means only that the school may enter pupils for those exams. A membership is neither. In Samut Prakan, three of the ten schools name no accrediting body at all, one is disputed between two different accreditors, one is somewhere between membership and accreditation, and one displays an IB logo its status does not support.

Individual school profiles

Every school in the table above has a full profile — campus address, stage-by-stage pathway, accreditations, religious character, boarding, what changed recently, and what we could not verify.

Two clusters, not one corridor

Guides that describe Samut Prakan as a single school corridor are describing Bang Phli and forgetting Samrong. The distinction matters more than usual here, because the two clusters differ on the one thing that decides a school run: whether rail reaches you at all.

One honest gap worth naming: the province’s main school belt is in Bang Phli district, which our own area guides do not cover as a named neighbourhood. Our six Samut Prakan area guides are Bang Na, Samrong, Pak Nam, Bang Pu, Praeksa and Theparak. Bang Na is the closest guide we have to the Bangna-Trad school belt, and the Samrong guide genuinely covers the second cluster. We would rather say that than route you to a page that does not describe where you would actually live.

One more: only D-PREP publishes actual bus routes — Rama 2 to the motorway at On Nut and Prawet, and Bang Kaeo to Bangna-Trad to Srinakarin to Lasalle. Every other school here has a bus service with no published coverage. A catchment claim in a FAQ is not a route you can plan a lease around; Concordian’s list of neighbourhoods it “serves” is marketing copy, not a timetable. Ask for the route map.

Two name collisions that will cost you a phone call

TSI is not TSIS. TSI International School (tsi.ac.th, formerly Thai Sikh International School) is at Samrong Nuea on Thang Rotfai Sai Kao Road. Thai-Singapore International School (tsis.ac.th) is on Srinakarin Road, about seven kilometres away. Both are in Mueang Samut Prakan, both are British-influenced, both run to A Level, and their acronyms differ by one letter. Directory entries for the two appear to have been merged in places. Check the domain and the street address before you contact either.

BCCI is not BCIS. Bangkok-Chicago Christian International School (bcci.ac.th) is in Bang Mueang, Samut Prakan and names no accrediting body anywhere on its site. Bangkok Christian International School (bcis.ac.th) is in Suan Luang, Bangkok, and is a different institution. The Cognia accreditation that surfaces in searches belongs to the second school. Do not credit it to the first.

The same care applies to multi-campus groups. ASB, SISB, TSI and D-PREP each run more than one campus, and in three of those cases one campus is in Bangkok and one is in Samut Prakan with different provision. ASB Sukhumvit is in Watthana, Bangkok; only Green Valley is here. TSI Wongwianyai is in Bangkok and is primary only; only Bearing runs the secondary school. SISB Pracha Uthit is in Bangkok and is where SISB’s boarding and its entire secondary provision sit.

Bilingual and English Programme schools

Beyond the ten international schools, Samut Prakan has bilingual and English Programme options at a fraction of the cost. We name the ones we could verify exist rather than gesturing at “local bilingual schools” as a category — but we have not inspected them, and we have not verified their curricula or admissions in the way we have for the ten above.

Cost is not access. Thai English Programme streams are inexpensive and are recommended everywhere on price — and admission generally runs through an entrance examination, sat in Thai, on a fixed annual timetable. For a newly arrived foreign child with no Thai, that route is frequently closed regardless of budget. Ask about the examination, the language it is sat in and the application window before you count an EP place as an option.

How to test a school listing before you trust it

Samut Prakan is where we would most strongly advise this, because a school here closed and the listings did not notice. Three checks, in order. Does it have its own website domain? Is there a findable street address, with a sub-district and a district, not just a province? Is there a phone number that answers? Then a fourth, specific to this province: does the school’s own homepage carry a closure or rebranding notice? VERSO’s does. A directory entry does not become true because several directories repeat it — they copy each other, and AI-generated school round-ups copy them in turn.

Ask every school on your shortlist

• Is this school still operating, under this name, this year? Samut Prakan is the one province in this guide where a school on families' shortlists closed — VERSO ceased operations on 31 July 2026 — and directories still list it as enrolling. Check the school's own homepage for a closure or rebranding notice before you do anything else.
• What qualification does a Grade 12 or Year 13 leaver actually hold? Not the curriculum label — the qualification. Raffles moved from Advanced Placement to the IB Diploma without the directories noticing, TCIS displays an IB logo while holding only candidate status, and D-PREP names no leaving qualification at all.
• Where does this school stop? SISB Suvarnabhumi ends at Primary 6 and awards nothing, despite being marketed across the Bang Kaeo property corridor as an international school.
• Is the school ACCREDITED, or AUTHORISED, or a MEMBER? Ask for the body, the status word and the expiry date. Three of the ten schools here name no accrediting body at all, one is disputed between WASC and NEASC, and one is somewhere between CIS membership and CIS accreditation.
• If boarding matters, is it a boarding house on this campus? SISB's boarding is real but sits at a different campus in Bangkok, and Concordian's residency programme cannot be confirmed as currently operating. ASB Green Valley and Wycombe Abbey are the ones publishing houses on site.
• Which province is the campus actually in, and which campus am I contacting? Almost every school here markets itself as Bangkok. Several groups run a Bangkok campus and a Samut Prakan campus under one brand with different provision — ASB, SISB, TSI and D-PREP all do.
• How long is the drive at 7am, from the address you are actually considering? The school belt spans kilometre 7 to kilometre 15 on Bangna-Trad plus a separate Samrong cluster. Those are not interchangeable at rush hour.
• Does the school publish a bus route that reaches you — or only a catchment claim? Only D-PREP publishes actual routes. Everyone else has a bus with no published coverage, which cannot be planned around.

What tuition costs

We publish no per-school fee figures, here or on any school profile, and we removed the ones this page used to carry. The reason is specific rather than squeamish: school fees change every year, most schools here publish only entry-level and top-tier bands rather than a grade-by-grade schedule, and third-party directories routinely quote figures that are tens of thousands of baht adrift from the school’s own current schedule. A stale number that looks authoritative is worse for your planning than no number at all. Request the current, complete fee schedule directly from each school’s admissions office, and ask specifically what sits outside tuition — registration, deposit, lunch, bus, activities, examination entry and capital levies are all commonly separate, and together they can move a budget materially.
