International Initiative for Impact Evaluation

3ie funds impact evaluations and systematic reviews that generate evidence on what works in development programmes and why.

3ie is an international grant-making NGO promoting evidence-informed development policies and programmes. We are the global leader in funding and producing high-quality evidence of what works, how, why and at what cost in international development. We believe that better and policy-relevant evidence will make development more effective and improve people’s lives.

Since its founding in 2008, 3ie has awarded over 200 grants (146 impact evaluations, 33 systematic reviews and 38 other studies) in over 50 countries, with a total value of US$84,225,205. 

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.
