Overview
Concordian International School, founded in 2001 and relocated to its purpose-built Bangkaew campus in 2006, is a full IB World School authorised for the Primary Years, Middle Years and Diploma Programmes -- one of only a handful of schools in Thailand offering the complete IB continuum. It is also one of the only genuinely trilingual IB schools in the greater Bangkok area, teaching in English, Chinese and Thai as co-equal instructional languages from Pre-Kindergarten through Grade 5, before shifting to English-medium instruction with Chinese and Thai continuing as language subjects through Grade 12. The Bangkaew campus sits on the Bangna-Trad Road corridor in Samut Prakan, roughly 10 minutes from central Bangkok and 15 minutes from Suvarnabhumi Airport.

FAQ
Where is Concordian International School located?
918 Moo 8, Bangna-Trad Road km 7, Bangkaew, Bang Phli District, Samut Prakan 10540 -- about 10 minutes from central Bangkok and 15 minutes from Suvarnabhumi Airport.
What curriculum does Concordian follow?
The full International Baccalaureate continuum -- Primary Years Programme (PYP), Middle Years Programme (MYP) and the IB Diploma Programme -- delivered through a genuine trilingual English/Chinese/Thai model through Grade 5, before shifting to English-medium instruction (with Chinese and Thai continuing as subjects) from Grade 6 to Grade 12.
Is Concordian accredited?
Yes -- authorised by the International Baccalaureate Organisation for all three programmes, and additionally accredited by the New England Association of Schools and Colleges (NEASC), the Council of International Schools (CIS), and the Thai Ministry of Education.
How much does Concordian cost?
We do not publish per-school fee figures. Fees change annually, Concordian publishes bands rather than a complete grade-by-grade schedule, and third-party directories routinely quote numbers well adrift from a school's own current figures -- a stale number that looks authoritative is worse for your planning than none. Request the current schedule directly from admissions, and ask what sits outside tuition: registration, deposit, examination entry, activities and transport are commonly separate.
Does Concordian offer boarding?
Treat it as unproven. The school's navigation carries a 'Residency Boarding Program' item, but the page itself contains no descriptive text at all -- no ages, eligibility, house staff, application process or fees -- and was last modified in March 2021. The only substantive description sits inside a 2019 publication behind an unreadable embedded viewer. Ask admissions directly whether residency is operating this year before treating Concordian as a boarding option. Note that the school's own quick-facts row simultaneously describes it as a 'day school'.
