Millions Learning, a project of the Center for Universal Education (CUE) at the Brookings Institution, addresses the question of how to scale quality education for all children and youth. CUE is launching Real-time Scaling Labs in partnership with local institutions in a number of countries and U.S. cities to generate more evidence and provide practical recommendations around the process of scaling in global education, encouraging a stronger link between research and practice. This report provides an overview of the labs' methodology, approach, and design.
