The International Baccalaureate Organization

The International Baccalaureate (IB), formerly known as the International Baccalaureate Organization (IBO), is a nonprofit foundation headquartered in Geneva, Switzerland, and founded in 1968. It offers four educational programmes: the IB Diploma Programme and the IB Career-related Programme for students aged 15 to 19, the IB Middle Years Programme for students aged 11 to 16, and the IB Primary Years Programme for children aged 3 to 12. To teach these programmes, schools must be authorized by the International Baccalaureate.

P.S. everything is a CAS experience.
