This report describes the mechanisms and practices that support evidence-based policy-making and it covers the member countries of the Eurydice network. It examines both the public and private institutions that can provide evidence for policy-makers. It does not include evidence used for assessing policies i.e. evaluations, except in the cases where the evaluation of a previous policy is explicitly used as evidence for policy reform. This report is only intended to provide an initial mapping of the support mechanisms for evidence-based policy-making, but it could act as the basis for a more detailed analysis in the future.
