The International Baccalaureate Diploma Programme is a rigorous preuniversity course of study leading to examinations for highly motivated secondary school students between the ages of 16 and 19. The International Baccalaureate Organization (IBO) offers the diploma program for students throughout the world. Recognition of the diploma is slowly taking hold in the United States, where approximately 460 high schools are IB World schools. The program has successfully existed in other countries since 1968, and as American public schools look for quantitative methods to evaluate their programs, they are applying in greater numbers for membership in the IBO. In this article, the author gives a concise summary of the IB program, discusses the IB music history curriculum and requirements, and shares some thoughts on how implementation of the course and the program might affect the current music program.
