Increasingly, early education, regardless of setting type, is considered to be an educational intervention that sets the stage for children's long-term school success. Accordingly, policymakers are focused on how to develop and support educators who have the skills and capacity to deliver high-quality programming to children. A pressing question for the Massachusetts Department of Early Education and Care (EEC) and the driving question behind this report is: what kinds of coaching supports are effective at building the capacity of early childhood educators and, as a result, improving the quality of early education programming for children? In April 2017, Abt Associates was hired by the EEC to support the Department in the design of a system for the delivery of coaching-based technical assistance to early education and out-of-school time providers across Massachusetts. To accomplish this, Abt conducted four activities: (1) reviewed recent and relevant research and policy literature to determine the features and elements of a coaching model that evidence might support (literature review and annotated bibliography appear in Appendix A); (2) scanned statewide coaching models operating in other states (scan of state models appears in Appendix B); (3) inventoried Massachusetts's current state-level initiatives that have a coaching component (inventory appears in Appendix C); and (4) conducted a gap analysis, comparing findings from the review and scan versus Massachusetts's current coaching initiatives captured in the inventory. This report summarizes that work and provides recommendations, based on evidence and practice, for a proposed statewide model of coaching for early educators in Massachusetts. Chapter 2 summarizes findings from the three information-gathering activities and the gap analysis. The report concludes with recommendations for a proposed statewide coaching model (Chapter 3) and a preliminary implementation plan (Chapter 4).
