The purpose of this study is to analyze the impact of global governance on Korean educational policy. Globalization is a wide spreading phenomenon in educational policy. One of the critical factors contributing to the interdependent relationship within a domestic education policy-making processes is increasing power of international organizations. However, the influence of international organizations on domestic policy in countries is little noted, even though they play a critical role in making educational policy. In particular, the OECD (Organization for Economic Cooperation and Development) serves as influential global governance entities. After reviewing theoretical studies and reported evidence, we constructed a research framework, including two research questions. The results of the research revealed that 1) even though the OECD does not have compulsory power on the Korean government, the international organization has a long impact on Korean educational policies; and 2) the OECD has functioned as a facilitator of policy convergence. The researchers suggest that these meaningful findings have significant implications for policy research and theory. First, it is necessary to include international organizations as an influential policy actor within educational governance. Second, international organizations play a pivotal role in nation-states’ policy making. This means that as transnational governance by international organizations has functioned as a normative policy standard, global governance results from policy convergence and institutional isomorphism among nation-states. And last but not least, domestic policy decision makers conceive of policy recommendations and comparative data of the international organization as a kind of norm, standard, or [and] myth. These provide a basis for legitimizing educational policies when policy makers consider introducing new national policy on education. Paradoxically, it has the potential to negatively affect deliberative democracy.
