The Organisation for Economic Co-Operation and Development (OECD) and its Programme for International Student Assessment (PISA) play an important role in forming transnational education policy. Based on the results of the PISA measurements and other evaluations, the OECD can claim that its policy proposals are evidence based and in accordance with international standards. There is growing interest from the national governments to adapt their national policy strategies to these international standards. However, the translation from the transnational to national policy is a complex process, whereby the national receivers of the policy are selective regarding the policy elements they borrow from those who create and influence transnational policy. Thus, discursive power regarding transnational policy can be understood as power through ideas, making national reforms similar but not identical, and promoting incremental or imperceptible reforms.
