The purposes of this paper are to follow the development of the International Baccalaureate (IB), examine its aims and its methods for achieving those aims, and discuss the possible future paths which IB may take. International Baccalaureate is a secondary school which offers a curriculum and examination system that is relevant to the needs of an international student body and that is recognized by the university systems in the home countries of participating students. Plans for the IB were first drafted in 1964 at the International School of Geneva. Goals of IB were to (1) work within the framework of various international schools to produce agreement on an IB curriculum, (2) develop an efficient and reliable examination structure, and (3) achieve acceptance by a number of national universities to grant IB diploma holders the equivalent status of a student studying within the national educational system. Curriculum includes language; study of man (social studies); experimental sciences; mathematics; specialized electives; theory of knowledge; and cultural, aesthetic, and social services activities. Development of IB was completed in 1975 and it is now operating in almost 80 schools around the world. Appendices include notes and syllabi for a history course and a course on film making at the Copenhagen International School. (ND)
