The Development Evidence Portal (DEP) is the world’s largest database of impact evaluations and systematic reviews on interventions to improve lives in low- and middle-income countries. It is updated monthly and contains more than 10,000 impact evaluations, systematic reviews and evidence gap maps. The DEP provides advanced searching capabilities and a rich set of options for filtering studies to help you find the evidence you need.

We have engaged with more than 15 study team members working on evaluations in four countries across three continents to pilot-test and implement our TREE Review Framework that complements the necessary work of Institutional Review Boards. In this blog, we share initial lessons from this experience.

For each work area of the USAID’s Center for Democracy, Human Rights, and Governance, we have recently developed evidence gap maps and summarized the findings to provide an overview of the existing evidence. These maps and analyses of the differences and similarities between them aim to inform the agency's future programming.
