Impact evaluation refers to the range of methodologies that assess the extent to which outcomes observed can be attributed to a project, program or policy intervention. These outcomes may be in relation to uptake of public services, improved nutritional status, better test scores, higher incomes and so on. In contrast to outcome monitoring, which simply measures whether targets have been achieved, impact evaluations help us answer key questions for evidence-based policy making, namely, what works, what doesn’t, where, why and for how much. It is therefore integral to our efforts to improve the effectiveness of policies aimed at reducing child poverty, as well as of development efforts more generally in achieving outcomes.
