A partnership exploring how child care affordability, quality, and accessibility affect outcomes for families and children, with a key objective of understanding the effect of State policies such as level of subsidies, tiered reimbursement, and quality regulations. Questions addressed include: (1) How does quality vary for different subgroups, including families who receive subsidies and families from different cultural groups?; (2) How do subsidies affect parents' choice of care, the quality of that care, family earnings, and employment stability?; (3) How does tiered reimbursement affect quality?; and (4) How do subsidies affect the child care market in terms of supply, cost, and quality? Both quantitative and qualitative methods are used. Data from a statewide survey of representative households provides a unique picture of families' child care arrangements, including informal care. Longitudinal analyses of administrative data examine the effect of child care subsidies on employment and earnings.
