Range of responsibilities of policy evaluation co-ordinating institutionsHowever, overall, the Belgian federal government still faces many challenges that hinder an evidenceinformed policy-making approach (Belgian Court of Audit, 2018[5]). In particular, there is little co-ordination of evaluations across the federal government, and, as a result, limited opportunity for actors to share good practices, to conduct cross-sectorial evaluations in order to better understand the linkages and trade-offs between policy areas, to increase the overall production of evidence, and to create a critical mass of evaluation skills in the administration. Evaluation demand, both at a political level and at the level of the senior civil service, is also structurally low, thus affecting the impact of evaluative evidence on decisionmaking. This low demand ultimately impedes the incorporation of evidence into decision and policymaking and decreases incentives to strengthen evaluation mechanisms more broadly.In this context, this paper provides an analysis of the Belgian federal government's evaluation system. It provides a gap analysis of its practices on the institutionalisation, quality and impact of policy evaluations by comparing them to OECD members' good practices in this regard. The paper thus takes a wholistic approach to policy evaluation, which not only looks at individual evaluative practices, but also at how those can come together so that evaluation becomes an integral part of the policy cycle. Based on this comparative analysis, the paper also proposes concrete policy recommendations for improving the Belgian federal government's evaluation system.
