Concordian International School

Concordian International School is a unique institution in Bangkok, being the only school in Thailand to offer a full International Baccalaureate (IB) curriculum in a trilingual environment (English, Mandarin Chinese, and Thai). Founded in 2001, the school aims to develop compassionate, self-confident, and principled students who can navigate a multicultural world with ease.

From the Early Years through to the Diploma Programme, students are immersed in a rigorous academic environment that values cultural heritage as much as modern science and technology. The school is particularly famous for its Mandarin immersion program, which is widely considered the strongest in the country, attracting families who prioritize high-level fluency in multiple languages.

The campus in Bang Na is well-equipped with modern classrooms, a grand theater, and impressive sports facilities. Concordian is highly regarded for its community-oriented atmosphere and its consistently high IB Diploma results, sending graduates to top universities worldwide.
