This study will examine three implementation factors that prior research indicates may limit or enhance the success of these initiatives. The first implementation factor is that state and local CCDF administrators have sufficient data and tools to monitor and provide targeted support to programs implementing these initiatives. The second implementation factor is CCDF providers’ awareness and positive view of the state’s expulsion prevention policy and the available supports. The third factor is CCDF providers’ access to high-quality professional development and early childhood mental health consultation. We will use a mixed methods research study that includes: (a) analysis of extant state administrative data, (b) state-wide online surveys of providers of CCDF-funded programs (center-based program directors and providers and home-based child care providers), and (c) regionally-based case studies of CCDF providers and professional development specialists in six regions of the state. The three partners—AR DCCECE, SRI, and NCCP—have designed a set of study activities that produce and disseminate policy-relevant findings for a range of local state and national stakeholders during each of the project’s four years. The team will also engage in a set of structured activities to build the capacity of AR DCCECE to conduct rigorous policy-relevant research.
