The OECD/DAC defines evaluation as:
- a systematic, maximally objective assessment
- of an on-going or completed project, programme or policy
- and of its design, implementation and results
- whose aim is to determine the relevance and fulfilment of objectives, development efficiency, effectiveness, impact and sustainability.
An evaluation must provide information that is credible and useful, enabling the incorporation of lessons learned into decision-making by both recipients and donors.
The Special Evaluation Office for International Cooperation is tasked with the evaluation of all activities of the Federal State that are recognized as official development assistance by the Development Assistance Committee (DAC) of the Organisation for Economic Cooperation and Development (OECD).
