This chapter provides an introduction and critical discussion of the epistemic and ontological underpinnings of UNESCO, the OECD and the World Bank and gives an overview of the educational work of these three organizations from a global governance perspective. Based on their divergent ideologies and modes of governance, we conceptualize UNESCO as the “idealist”, the OECD as the “master of persuasion”, and the World Bank as the “master of coercion”. The chapter demonstrates how the three international organizations have engaged with similar ideas and approaches, collaborated when it served their interests and struggled for influence and impact on the design and workings of the global governance in education.
