The purpose of this highlight is to describe key findings from a research review on subsidy stability. The highlight defines key terms and provides an illustrative example, summarizes research on subsidy stability, describes potential administrative and policy obstacles that may make it harder for families to use subsidies, and shares resources for CCEE leaders interested in improving their subsidy programs. This information is particularly relevant for CCDF subsidies but is also applicable for other child care subsidy programs, such as state and local subsidy or scholarship programs. (author abstract)
