The grant team will evaluate the implementation and impact of DC’s innovative child care subsidy policies and practices, and how variations in payment policies and practices relate to access to stable, high-quality child care. The research questions for this project include: 1. What is the relationship between payment rate policies (e.g., differential rates based on the quality of the facility based on a cost estimation model) and access to child care? 2. How do provider payment policies affect availability and access to child care for families receiving subsidies and subsidy-eligible families? 3. How do provider payment practices affect availability and access to child care for families receiving subsidies and subsidy-eligible families? 4. How do family copayment policies affect access to child care? 5. What role do subsidy payment policies and practices play in improving equitable access to high-quality child care? 6. What are the outcomes and impacts of provider payments and family copayment policies and practices? The grant team will analyze administrative data and primary qualitative and survey data— collected from community leaders, policymakers, child care subsidy staff, providers, and families— to describe the implementation of policies and practices and produce evidence of outcomes and impacts.
