This article describes OECD ideological and policy changes that form the background for PISA. Furthermore, the author focuses on the OECD’s governance mechanisms and the obstacles it presents to public scrutiny. The author argues that the pursuit of market mechanisms posed both educational and political problems on the OECD's accountability regime. He argues that in order to redress the asymmetries between strong influence and weak democratic control will require profound advances in the organization of the global public sphere. He proposes to broaden the global educational discourse, in which the accountability narrative is complemented by narratives of local institutional learning, educational tradition, democratic participation, and cultural diversity.
