This brief is designed for school-based and community-based organizations interested in implementing evidence-based early childhood curricula. It provides practical guidelines and tools for four stages of implementation: (1) Preparing the system; (2) Hiring and training coaches; (3) Getting teachers ready to implement the curriculum as intended; and (4) Providing ongoing monitoring. The resources in this guide are derived from the technical assistance MDRC has provided to coaches and programs in several large-scale studies that have evaluated early childhood supplemental curricula and found positive effects on children's outcomes. Programs interested in using these resources can pull out individual tools or guides that meet their specific needs.
