This chapter aims at understanding the role of the OECD in the development and international dissemination of SAWA policies. Specifically, the chapter analyses the governance mechanisms through which these reforms are being promoted by the OECD, namely, data gathering, education policy evaluation, and the generation of policy ideas through different knowledge products and policy spaces. Methodologically, the chapter is based on a systematic literature review of a corpus of 33 papers, which we triangulate with official documents produced by the OECD. The chapter is structured as follows. In the first part, we present our research framework, which covers both our theoretical approach and our methods. In the second part, we present our main results, which we organize according to the different governance mechanisms articulated by the OECD around SAWA reforms. In the last part, we pick up the main points in a concluding discussion.
