3ie Development Evidence Portal
The Development Evidence Portal (DEP) is an expansive and growing repository of rigorous evidence on what works in international development. It contains high-quality impact evaluations, systematic reviews, and evidence gap maps and is the most comprehensive resource for this kind of evidence from low- and middle-income countries. We maintain this portal as a global public good and ensure it is updated frequently. We are committed to keeping it this way.

3ie has documented the interventions evaluated and the outcomes measured in thousands of studies in our evidence portal. These interventions and outcomes are organised into a hierarchical taxonomy to make it easy to find relevant evidence. Use the taxonomy explorer to identify the interventions/outcomes of interest to you, then use them to search or filter for studies on the portal.
