We are a leader in supporting the production, synthesis and uptake of high-quality evidence on what works in social and economic development. Established in 2008, we provide services and expertise to address the knowledge needs in the development sector and to help decision making in governments, NGOs, foundations, international development institutions and others working in low- and middle-income countries. We work across a wide range of sectors including agriculture, education, health, nutrition, sanitation, livelihoods, climate change and peacebuilding, among others. In all our work we believe transparency, reproducibility and ethics are core considerations and we have developed tools to bolster these efforts.
