The purpose of the Initial Effects of Child Care Reauthorization on Child Care Markets project is to understand early implementation issues related to the Child Care and Development Block Grant (CCDBG) Act of 2014 by examining existing data, gathering new data, discussing key issues, and hearing from individuals on the ground who are directly affected by subsidy policies and reauthorization changes. This paper 1) provides an overview of the existing literature on child care stakeholder experiences with the child care market and subsidy system to date, 2) summarizes state approaches to implementing policy changes as outlined by the reauthorization, and 3) summarizes considerations and themes that were discussed during a 2019 convening of state child care policy administrators, representatives from child care national organizations, researchers, and federal staff. This paper uses existing research literature, an analysis of state policy data and stakeholder input to highlight key issues related to implementation of Child Care and Development Fund (CCDF) reauthorization on states, providers and families.
