Evaluation is widely recognised as an important component for learning and improving development effectiveness. Evaluation responds to public and taxpayer demands for credible information and independent assessment of development co-operation activities. The Development Assistance Committee's Network on Development Evaluation supports members in their efforts to strengthen and continuously improve evaluation systems. The 2016 review of evaluation systems in development co-operation looks at the changes and trends in evaluation systems over the last five years. The report describes the role and management of evaluation in development agencies, ministries and multilateral banks. It provides information about the specific institutional settings, resources, policies and practices of Dac Evaluation Network members, and includes specific profiles on each member's evaluation system. The study identifies major trends and current challenges in development evaluation. It covers issues such as human and financial resources, institutional setups and policies, independence of the evaluation function, reporting and use of evaluation findings, joint evaluation, and the involvement of partner countries in evaluation work. This report is part of the Dac Network on Development Evaluation's ongoing efforts to increase the effectiveness of development co-operation policies and programmes by promoting high-quality, independent evaluation.
