The Geneva-registered International Baccalaureate (IB) celebrated its 50th anniversary as an organisational entity in 2014, having first appeared in 1964 as the International Schools Examination Syndicate. In January 2015 the 5,000th programme had appeared at a school in Albania. The IB, now offering four programmes, has moved significantly over recent years into state funded schooling, especially in the United States, and Ecuador. At the same time there has been no significant growth in Africa where the operational paradigm remains largely unchanged since the 1980s. The 76 schools in 25 countries located across the continent of Africa in mid-2015 accounted for just 1.8 per cent of all schools worldwide. Twelve countries in Africa had a solitary "international school" offering the IB programmes. This paper is the first to address this situation. This article reveals the growth and extent of IB activity across Africa, and offers possible reasons for the ongoing dearth of schools.
