Impact evaluation is an empirical approach to estimating the causal effects of interventions, in terms of both magnitude and statistical significance. Expanded use of impact evaluation techniques is critical to rigorously derive knowledge from development operations and for development investments and policies to become more evidence-based and effective. This guide is a practical resource for people interested in generating or using high-quality evidence on what works in international development. The authors highlight core concepts, methods and practical rules of thumb on how to implement successful evaluations for technical and non-economist audiences.
