What works to improve learning at scale?

This brief presents findings on what worked to improve learning outcomes at scale under 8 successful early grade literacy programs, with a focus on findings from the Tusome program in Kenya. These findings were generated as part of the Learning at Scale study, conducted by RTI International with the Center for Global Development and funded by the Bill and Melinda Gates Foundation. The findings from Learning at Scale are organized into three categories: instructional practice, instructional support, and system support.
