The International Initiative for Impact Evaluation (3ie) is a global leader in funding, producing, quality assuring and synthesising rigorous evidence. We support studies and reviews that examine what works, for whom, why and at what cost in low- and middle-income countries (L&MICs). We are also a global advocate for the generation and use of quality evidence in development decision-making.
3ie is a membership organisation with a global network of members and key partners.
3ie promotes evidence-informed equitable, inclusive and sustainable development. We support the generation and effective use of high-quality evidence to inform decision-making and improve the lives of people living in poverty in low- and middle-income countries. We provide guidance and support to produce, synthesise and quality assure evidence of what works, for whom, how, why and at what cost.
Since its founding in 2008, 3ie has awarded over 300 grants (249 impact evaluations, 38 systematic reviews and 23 other studies) in over 50 countries, with a total value of US$125,164,797.
3ie has offices in New Delhi, London and Washington, DC. The three main funders of 3ie are the Bill & Melinda Gates Foundation, UKaid through the Department for International Development and the William and Flora Hewlett Foundation.
