The International Baccalaureate Curriculum was introduced by the International Baccalaureate Organisation (IBO) in 1968. The curriculum is well-known for its academically progressive and rigorous programmes at primary, secondary and pre-university levels. These programmes are the Primary Years Programme (IB PYP), Middle Years Programme (IB MYP), Diploma Programme (IBDP) and Career-related Programme (IB CP). The International Baccalaureate Curriculum has gained recognition around the world especially in Asia. A number of international schools in Southeast Asia are recognised as IB World Schools by the IBO.
