The purpose of this study is to integrate extant state child care quality and TANF longitudinal datasets to investigate policy relevant research on child care subsidy, child care quality, and child and family well-being. Specifically, this secondary analysis study provides the opportunity to examine the associations between global quality scores and subsidy utilization across four program types (school-age, infant/toddler, family child care, and preschool) over a four year period. Further, quality data has been matched with a subset of TANF participants to examine longitudinally the relationships between child care quality and family reported child and family well-being indicators. Research questions include: (1) What is the relationship between subsidy density and global program quality?; (2) How does the receipt of child care subsidies affect child and family well-being?; (3) How are child care arrangements influenced by TANF participation patterns?, and (4) What are the relationships between child and family well-being, child care subsidy and program quality?
