Samut Prakan's international-school field is small but genuinely strong, anchored by two established campuses on the same Bangna-Trad Road corridor in Bangkaew: Concordian International School, a full IB World School built on real trilingual immersion, and Raffles American School Bangkok, a WASC-accredited American-curriculum school just steps from the Bangkok border. Fees are 2026 guide figures in Thai baht (≈ THB 35–36 = USD 1).
Samut Prakan sits just south of Bangkok proper, and its international-school field reflects that: rather than a large city-scale market, it has two well-established, genuinely differentiated schools sharing the same Bangna-Trad Road corridor in Bangkaew, Bang Phli district. Concordian International School, open since 2001, is a full IB World School (PYP, MYP and Diploma Programme) and one of the few schools in the greater Bangkok area running true trilingual immersion in English, Chinese and Thai through Grade 5. Raffles American School Bangkok, established in 2012 about 100 metres from the Bangkok city line, runs a WASC-accredited American curriculum toward a U.S. high school diploma, with Advanced Placement courses in the upper grades. Two further options round out the field: SISB Suvarnabhumi Campus, a Nursery-to-Primary Singapore-curriculum school near Suvarnabhumi Airport, and D-PREP International School, an American-curriculum school near Mega Bangna founded by the Didyasarin family. Below: what each school offers, published tuition for both, where to base yourself, and admissions tips. For day-to-day budgeting pair this with the Samut Prakan cost-of-living guide, and use the Samut Prakan hub to match a neighbourhood to your school.
The two international schools serving Samut Prakan province and the Bangkok-border districts around it. This is a starting point, not a ranking — the right fit depends on curriculum, language priorities and budget.
| School | Area | Curriculum | Known for |
|---|---|---|---|
| Concordian International School | 918 Moo 8, Bangna-Trad Km 7, Bangkaew, Bang Phli District, Samut Prakan 10540 — about 10 minutes from central Bangkok and 15 minutes from Suvarnabhumi Airport | International Baccalaureate: PYP, MYP and IB Diploma Programme, delivered through a trilingual English/Chinese/Thai model | Founded in 2001 by school sponsor Varnnee Chearavanont Ross and relocated to its current Bangkaew campus in 2006, Concordian now educates roughly 1,100 students from Pre-Kindergarten through Grade 12. It is a genuine full-immersion trilingual school — English, Chinese and Thai are all teaching languages from Pre-K through Grade 5 — before shifting to full English-medium instruction from Grade 6 to Grade 12, with Chinese and Thai continuing as additional-language subjects. Concordian is authorised by the International Baccalaureate Organisation for all three programmes and is additionally accredited by the New England Association of Schools and Colleges (NEASC), the Council of International Schools (CIS), and the Thai Ministry of Education. |
| Raffles American School Bangkok | Moo 15, Bangna-Trad Road, Bangkaew, Bang Phli District, Samut Prakan 10540 — about 100 metres from the Bangkok city border | American curriculum with a U.S. high school diploma track, incorporating Advanced Placement (AP) courses; WASC-accredited | Established in 2012, Raffles American School (RAS) serves students aged 2 to 18 — Nursery through Grade 12 — across two purpose-built campuses on the same site: a Preschool & Elementary campus (Nursery to Grade 4) and a separate Middle & High School campus (Grade 5 to 12). Instruction is in English throughout, following an American curriculum that leads to a U.S. high school diploma, with Advanced Placement courses available in the upper grades. The school holds accreditation from the Western Association of Schools and Colleges (WASC), the U.S. accreditor most American-curriculum schools in Thailand rely on. |
| SISB Suvarnabhumi Campus | 4/5 Moo 5, Namdaeng-Bangplee Road, Bangkaew, Bang Plee District, Samut Prakan 10540 — near Suvarnabhumi Airport | Hybrid UK/Singapore at Nursery-Kindergarten; Singapore curriculum in Primary (ages 2-12) | A Nursery-to-Primary campus of Singapore International School (SISB), teaching English, Chinese and Thai from Nursery 1 and the Singapore curriculum -- renowned for Mathematics and Science results -- from Primary 1. After Primary 6, students transfer to SISB's Pracha Uthit Campus in Bangkok for Sixth Form (Cambridge IGCSE, then AS/A-Levels or the IB Diploma). One of six SISB campuses nationwide, operated by SET-listed SISB Schools. |
| D-PREP International School | Bang Kaeo (Primary, Nursery-Grade 5) & Bang Phli Yai (Secondary, Grades 6-12, opened 2024), Bang Phli District, Samut Prakan 10540 — near Mega Bangna | American curriculum with Reggio Emilia Early Years, IB Primary Years Programme, Expeditionary Learning Middle School and AP-supported High School; WASC-accredited | Founded in 2018 by Ms. Lady Didyasarin Tavedikul of the Didyasarin family (founders of the American School of Bangkok), D-PREP runs two purpose-built campuses near Mega Bangna and is part of the XCL Education group. |
Concordian's IB pathway sits at a premium price point; Raffles' American-curriculum track is considerably more affordable. Figures below are each school's published entry-level and top-tier bands for the 2026 academic year — exact fees for intermediate grades vary and should be confirmed directly with admissions.
Concordian International School
| Level | Annual tuition |
|---|---|
| Pre-Kindergarten / Kindergarten (entry levels) | THB 626,400 / year |
| Grades 11–12 (IB Diploma Programme, top tier) | THB 963,400 / year |
Raffles American School Bangkok
| Level | Annual tuition |
|---|---|
| Nursery (age 2+, entry level) | THB 198,000 / year |
| Grades 5–12 (top tier) | THB 297,000 / year |
| Additional fee | Amount |
|---|---|
| Lunch fee (all grades, annual) | THB 30,000 / year |
Both figures are published entry-level-to-top-tier bands, not a full grade-by-grade schedule — always request the current, complete fee schedule directly from each school before you commit to an enrolment. Neither school's published pricing online breaks out every intermediate grade, so budget toward the top of the range if your child will be entering the senior grades.
Unlike cities with a genuine multi-school spread, both Samut Prakan schools sit on the same corridor — so the "where to live" decision is really about how close to the Bangkok border you want to be:
| Area | Nearest school(s) | Why families live there |
|---|---|---|
| Bangkaew / Bang Phli district | Concordian, Raffles American School, SISB Suvarnabhumi Campus & D-PREP International School | All four schools sit within Bang Phli District along the Bangna-Trad Road / Mega Bangna corridor — Concordian and Raffles in Bangkaew near the Bangkok border, SISB Suvarnabhumi near Suvarnabhumi Airport, and D-PREP near Mega Bangna. This is the single school-driven cluster in Samut Prakan; families typically base themselves along this corridor or in nearby Bangna on the Bangkok side of the border to shorten the commute. |
Concordian International School suits families who want a genuine IB pathway from Pre-K through the Diploma Programme and see real value in trilingual immersion — English, Chinese and Thai as teaching languages through Grade 5, giving children an unusually strong foundation in Chinese specifically, before the school shifts to English-medium instruction with Chinese and Thai continuing as subjects from Grade 6. It carries a premium tuition to match. Raffles American School Bangkok suits families anchored on a U.S. high school diploma and Advanced Placement pathway, want WASC accreditation (the standard U.S. accreditor most American-curriculum schools in Thailand use), and prefer a meaningfully lower price point, with split Preschool/Elementary and Middle/High School campuses on the same site. Both schools sit within a short drive of each other on Bangna-Trad Road, so families are not forced to choose a different part of the province depending on which curriculum they pick.
Both schools are established and mid-sized (Concordian educates roughly 1,100 students), so capacity is rarely the binding constraint — the bigger task is matching curriculum and language priorities to your child, then confirming the exact fee schedule directly, since both schools publish only entry-and-top-tier tuition bands online rather than a full grade-by-grade table. At Concordian, ask admissions how the Chinese-language immersion track is structured for a child with no prior Mandarin exposure, since this is the school's core differentiator. At Raffles, ask about the Advanced Placement course list actually offered in a given year, and confirm the lunch-fee and any additional activity or bus fees on top of the published tuition band. Gather school reports, immunisation records and references before you leave your home country, and confirm whether an employer relocation package covers tuition before you commit to a lease or a school. Because both schools sit right at the Bangkok–Samut Prakan border, also compare commute times from Bangna and On Nut on the Bangkok side, not just from within Samut Prakan itself.
Samut Prakan's two established international schools serve different priorities. Concordian International School is a full IB World School (PYP, MYP and Diploma Programme) built around genuine trilingual immersion — English, Chinese and Thai are all teaching languages through Grade 5, shifting to English-medium from Grade 6. Raffles American School Bangkok runs a WASC-accredited American curriculum leading to a U.S. high school diploma, with Advanced Placement courses in the upper grades. There is no single 'best' school — the right fit depends on whether you want an IB pathway with genuine language immersion or an American-diploma track, and on your budget.
Concordian International School's published fees range from about THB 626,400 a year at the entry (Pre-K/Kindergarten) levels up to THB 963,400 a year for Grades 11–12 in the IB Diploma Programme. Raffles American School Bangkok is significantly less expensive, ranging from about THB 198,000 a year for Nursery up to THB 297,000 a year for Grades 5–12, plus a separate THB 30,000-a-year lunch fee. Both figures are the published entry-level and top-tier bands — fees for intermediate grades vary and should be confirmed directly with each school's admissions office before you budget.
Yes — Concordian International School in Bangkaew is a full IB World School, authorised to teach the Primary Years Programme (PYP), Middle Years Programme (MYP) and the IB Diploma Programme, and is additionally accredited by NEASC, the Council of International Schools and the Thai Ministry of Education. It is also one of the few genuinely trilingual IB schools in the Bangkok area, teaching in English, Chinese and Thai through Grade 5.
Yes — Raffles American School Bangkok, established in 2012 on Bangna-Trad Road about 100 metres from the Bangkok border, follows an American curriculum leading to a U.S. high school diploma, offers Advanced Placement courses, and is accredited by the Western Association of Schools and Colleges (WASC).
Both Concordian International School and Raffles American School Bangkok sit within a few kilometres of each other on the Bangna-Trad Road corridor in Bangkaew, Bang Phli district — Concordian at kilometre 7, Raffles roughly 100m from the Bangkok city line. Families choosing either school typically base themselves along this corridor or in neighbouring Bangna on the Bangkok side of the border, which keeps the daily commute short while staying close to BTS Sukhumvit-line access and Suvarnabhumi Airport. See our Samut Prakan hub for the fuller area breakdown.
