This project seeks to understand how child care subsidy payment rates and family co-payments affect parents’ access to affordable child care that meets their needs and supports children’s development. In addition, this project aims to understand whether administrative burdens mediate the impact of changes in the generosity of payments to providers and family copayments on outcomes of interest. During this planning project, the project team will engage Michigan stakeholders through advisory groups, develop and test key instruments, identify data sources for a potential evaluation, and conduct preliminary analyses of administrative data. Expected outputs of this planning project include piloted instruments for primary data collection in the evaluation, a list of variables available for secondary data analysis, preliminary analyses of equity of access, and plans for a mixed-method longitudinal analysis of reimbursement and co-payment policies’ impact on equal access to child care subsidies.
