A trilingual full-IB World School on the Bangna-Trad Highway in Samut Prakan, on Bangkok's eastern edge. Concordian runs English and Chinese immersion from Pre-K through Grade 5, then an English-medium IB pathway with continued Chinese and Thai study through Grade 12 — a distinctive option for families prioritising Mandarin alongside an international curriculum.
The campus, and how you actually get there
Address: 918 Moo 8, Bangna-Trad Road Km. 7, Bang Kaeo, Bang Phli, Samut Prakan
A purpose-built campus on the Bangna-Trad corridor, positioned for the eastern suburbs and airport-side families rather than the city centre.
Getting there: No rail at the campus. It sits on the Bangna-Trad highway in Samut Prakan — quick to Suvarnabhumi Airport by road, but a drive or school bus from anywhere in Bangkok.
Bangkok school runs are decided by traffic, not distance. Cross-check with the Bangkok getting-around guide and the BTS and MRT network before you commit to a neighbourhood.
The curriculum pathway
How a child progresses through the school, stage by stage:
- Trilingual immersion (English, Chinese, Thai) from Pre-K to Grade 5
- IB Middle Years Programme, English-medium, with continued Chinese and Thai
- IB Diploma Programme to Grade 12
Accreditation & memberships
Accreditation is the closest thing to an objective quality signal in international schooling — it means an outside body has inspected governance, teaching and safeguarding. BAANLYY does not rank schools, so this is what Concordian International School and its accrediting bodies publish, not our verdict:
- IB World School (PYP / MYP / DP)
- Council of International Schools (CIS)
- New England Association of Schools and Colleges (NEASC)
Boarding and the size of the school
Boarding: Day school — no boarding.
Scale: Reported at around 1,100 students, with a Mandarin-motivated cohort that gives the school a different profile from its British and American neighbours. Roll and nationality figures move every year and schools report them differently — treat these as indicative and ask the admissions office for the current numbers.
Who this school tends to suit
Families who want genuine Mandarin fluency alongside the IB, Chinese-speaking and regional families, and eastern-suburb or airport-side households.

Living near Concordian International School
Concordian is technically in Samut Prakan. The eastern Sukhumvit tail and Bang Na are the realistic catchment.
Check the school's bus catchment before you sign — a home that looks close on a map can sit outside the route, and a home on the route can be twenty minutes further away and still be the easier morning.
What to confirm directly with the school
BAANLYY deliberately does not publish per-school tuition figures: they change annually, schools publish their own current schedules, and a stale number is worse than none. Take this list to the admissions office:
- How the language-immersion ratio changes by grade — the balance of English, Chinese and Thai shifts as children move up, and it is the main reason families choose or leave.
- The current fee schedule — tuition, application and registration fees, any refundable deposit or capital/development levy, uniforms, lunches, the bus and trips.
- Whether the year group you need has a place, or a waitlist, for your intended start date.
- School bus routes, catchment zones and pick-up times for the neighbourhood you are considering — these matter more than straight-line distance in Bangkok traffic.
- Entry requirements: assessments, interviews, English-language support and the school reports or transcripts you must supply.
