Introduction

Concordian International School, founded in 2001 and situated along the Bangna‑Trad Highway, is a full Pre‑K to Grade 12 IB World School educating around 1,100 students in Greater Bangkok, Samut Prakan . From Nursery to Grade 4, children learn via a trilingual immersion program—roughly 45 % English, 40 % Chinese and 15 % Thai—and from Grade 5 onwards the curriculum transitions to fully in English, with Chinese and Thai as academic subject languages . The school offers all three IB programmes, PYP, MYP, DP, and typical class sizes are 16–18 students. Facilities include multiple sports venues (pools, courts, gyms), with strong participation in AISAA competitions . Unique to Concordian is its Chinese‑English immersion in early years, supported by a wide range of clubs, from robotics, chess, community service, and performing arts to Chinese language and yoga.
