Page "IB Diploma Programme" Paragraph 9

The first six years the IB offered the IB Diploma Programme is referred to as the " experimental period ".

The experimental period was designed to extend for six years and to include a limited population of students.

Each school was to be inspected by ISES or IBO and had be school approved by their government.

The experimental period ended in 1975, and in that year the International Baccalaureate North America ( IBNA ) was established as a separate entity, allowing the funding for implementation of the IBDP to remain in the country rather than being sent to Geneva.

The first official guide to the programme containing its syllabus and official assessment information, was published in 1970 and included the theory of knowledge course.

The extended essay was introduced in 1978, but creativity, action, service ( CAS ), although mentioned in guides beforehand, was not specifically identified in the guide until 1989.
