This paper aims to survey the current landscape of education policy evaluation across OECD countries and economies by examining recent trends and contextual factors that can promote more robust education policy evaluation, as well as identifying key challenges. It takes a view of policy evaluation as an activity that takes place throughout the entire policy cycle, before, during, and after a reform is implemented. It proposes a supporting framework for education policy evaluation that integrates institutional factors which can help to build robust underpinnings for policy evaluation. It also presents some specific considerations to take into account for individual policy evaluation processes. Analysis of more than 80 evaluations across OECD education systems provides an indication of the diversity of approaches taken in the policy evaluation process. Key findings refer to the “who”, “when”, “what”, “how”, “for what” and “what next” of policy evaluation processes through a comparative lens.
