To support and better understand how to scale effectively, in 2020, the Millions Learning project at the Center for Universal Education (CUE) at Brookings 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, multiteam, design-based research and professional support initiative called Research on Scaling the Impact of Innovations in Education (ROSIE). Since 2021, ROSIE has brought together 15 researcher and practitioner teams working in 30 low- and middle-income countries to study the process of scaling education initiatives for impact. This brief reflects on the 15 KIX teams' experiences to shed light on the role of champions in the scaling process. The brief introduces a typology of champions and ways of working with them as it also shares examples of how scaling teams are identifying champions and managing common challenges to the engagement of champions (such as time constraints, personnel turnover, and cultural dynamics).
