Impact Evaluation to Development Impact (i2i) is a World Bank multi-donor trust fund program launched in March 2014 with support from the United Kingdom’s Department for International Development (DFID). i2i’s mandate is to generate high-quality and operationally relevant impact evaluation (IE) research to transform development policy, help reduce extreme poverty, and secure shared prosperity. Its objective is to increase the use of IE in the design and implementation of public policy, strengthen country institutions for evidence-based policy-making, and generate knowledge in strategic development areas. The program aims to serve as a global platform to build donor partnerships in expanding the use of IE across the developing world. i2i is managed and delivered by the Development Impact Evaluation unit (DECIE) in the Research Group of the World Bank and adopts a bank-wide governance structure that comprises the bank’s regions and global practices.
