This case illustrates how the work of leaders and analysts in the Delaware Department of Education (DDOE) and the agency’s partnership with the Strategic Data Project (SDP), a program of the Center for Education Policy Research at Harvard University, created momentum for statewide policy change. By exploring Delaware leaders’ use of data and analytics to challenge assumptions and inform the development of better policies and practices, the case illustrates the importance of leadership, analytic and technical competency, and strategic partnerships when leading education reform. The case specifically highlights the power of human capital analytics to diagnose the current status of Delaware’s educator pipeline, from preparation through development and retention, and how effectively communicating with these analyses built coalitions of support and drove a culture of data use at both the state and district level.
