3ie seeks to improve the lives of poor people in low- and middle-income countries by providing, and summarizing, evidence of what works, when, why and for how much.

3ie’s work will address the enduring questions of development. Evidence will be collected from synthetic reviews of existing evidence, updated as new evidence appears. 3ie operates a grant program, financing impact studies in low- and middle-income countries, and supports quality impact evaluation through its quality assurance services.
