Samenvatting

Studying the impact of development interventions is not straightforward. Simple comparisons fall short, because differences in, for example, poverty are often not due to just the intervention, but also to other factors. In this article, we discuss examples of projects that studied the impact of interventions in a meaningful and reliable way. We then discuss some practical challenges. We call for a critical approach to impact evaluation designs and for a joint search for opportunities to evaluate impact in a meaningful and reliable way.
