Cambridge Assessment International Education (CAIE), founded in Britain in 1858, is the world's largest provider of international education programmes and qualifications. Currently, the organisation is affiliated with over 10,000 schools across more than 160 countries. This essay shows that of the approximately 956 CAIE schools in Africa, 888 are located in countries formerly colonised by Britain. Concerned by this association, I employ the concept of coloniality to analyse CAIE's colonial history and critiqued curricula. Addressing these topics individually and in tandem, I argue that the organisation is perpetuating coloniality in present-day Africa. CAIE claims it sets the global standard for international education. If this is indeed true, and there is evidence of coloniality in CAIE's history and practices, then there are grave implications for international education. Due to the remarkable dearth of literature that critically examines the organisation, I point to existing research that can help shape future studies of CAIE.
