The International Baccalaureate (IB), formerly known as the International Baccalaureate Organization (IBO), is an international educational foundation headquartered in Geneva, Switzerland and founded in 1968.
It offers three educational programmes: the IB Diploma Programme and the IB Career-related Programme for students aged 16 to 19, the IB Middle Years Programme, designed for students aged 11 to 16, and the IB Primary Years Programme for children aged 3 to 12.
To teach these programmes, schools need to be authorised by IB.
The organization's name and logo were changed in 2007 to reflect a reorganisation. Consequently, "IB" may now refer to the organisation itself, any of the four programmes, or the diploma or certificates awarded at the end of a programme
