Researchers from the Harvard Graduate School of Education (Catherine Snow and Nonie Lesaux, Co-Investigators) are conducting a project in partnership with MDRC, the University of Michigan and the Boston Public Schools. The project, called ExCEL (Expanding Children’s Early Learning), is designed to identify policies, classroom-level factors, and school experiences that are associated with children's school success during preschool and early elementary school grades. This project is funded by the Institute of Education Sciences.
