Evaluation is a key learning tool for the European Commission’ to understand not only what works and what does not, but why and under what circumstances. Evaluations generate knowledge and produce evidence which we use to improve the way we engage with our partners and enhance the impact of our development cooperation. As one of the world’s largest donors, the European Union (EU) is a leading force in demonstrating the value of rigorous evaluation.

This handbook is a revision of the Methodology Guidance published in 2006 and reflects the significant progress made in the field of evaluation over the past two decades. The handbook is a living document that will be adapted over time to reflect evolving practice and needs.
