Applying Evaluation Criteria Thoughtfully

Relevance, coherence, effectiveness, efficiency, impact, and sustainability are widely used evaluation criteria, particularly in international development co-operation. They help to determine the merit or worth of various interventions, such as strategies, policies, programmes or projects. This guidance aims to help evaluators and others to better understand those criteria, and improve their use. It starts by describing what they are, and how they are meant to be used. Then the definitions and concepts underpinning each criterion are explained. Finally, examples provide the reader with concrete ideas for using them.
