Since 2014, the Center for Universal Education (CUE) at the Brookings Institution has sought to address the challenges of scaling impact in education through the Millions Learning project, which focuses on how and under what conditions quality education innovations scale. In 2020, Millions Learning joined the Global Partnership for Education’s (GPE) Knowledge and Innovation Exchange (KIX), a joint partnership between GPE and the International Development Research Centre (IDRC), to facilitate a cross-national, multi-team, design-based research and professional support initiative called Research on Scaling the Impact of Innovations in Education (ROSIE). ROSIE brings together researchers and practitioners working in 29 LMICs to study processes of scaling education initiatives and to deepen impact of their ongoing work. Parallel to this work of learning alongside these scaling researchers and practitioners, we are pursuing a complementary qualitative study on how governments identify, adopt, and support education innovations to scale. It is that national level decisionmaking study on which these summary findings focus.
