International Baccalaureate International Schools in Thailand

30 schools in Thailand offer the International Baccalaureate.

What is the International Baccalaureate?

The International Baccalaureate (IB) is a Geneva-based framework spanning the Primary Years Programme (PYP), Middle Years Programme (MYP), and Diploma Programme (DP), with the DP recognized for university admission worldwide. IB schools are inspected and authorized directly by the IB organization, and the curriculum emphasizes inquiry-based learning, a broad subject spread, and an extended essay or research project at Diploma level.
