More than 150 countries around the world offer school pupils the opportunity to take the international baccalaureate (IB) rather than qualifications from their own education systems.
The IB is a series of educational programmes for students aged from three to 19. It was originally created to serve a mobile international clientele, such as the children of diplomats, who needed a kind of academic passport as they moved from one country to another. In order to serve this transient population, the IB was primarily taught in private international schools around the world.
