This article aims to look at the concepts of internationalism and international education through the lens of postcolonial theory, arguing that the fundamental aims of international education are obstructed as it remains a concept locked in the idea of the nation state that has not evolved with the ideas of major postcolonial theorists. However, through careful curricular choices within the International Baccalaureate (IB) academic programmes, international education in practice can transcend its theoretical limitations.
