The BIAS team worked with two states to design four tests focusing on two points in the CCDF process: when parents are applying for the program and when they must renew their eligibility. Problem Focus 1: Applying for a Subsidy -- Provider Choice Parents using a child care voucher must choose a child care provider. Some states have a Quality Rating and Improvement System (QRIS), which is designed, in part, to provide a standardized rating of provider quality. Since participating providers must meet a minimum standard of quality, the ratings may help parents select a provider. Administrators in Indiana were interested in increasing the number of parents who used their CCDF subsidies to pay for QRIS-participating providers, especially those with higher ratings. Problem Focus 2: Subsidy Renewal States require parents to periodically document their continued eligibility for their child care subsidy. CCDF administrators in Indiana and Oklahoma wanted to improve their respective renewal processes and increase the number of parents renewing on time. The following pages describe each state's problem(s) of interest, behavioral intervention design, and findings. First, provider choice in Indiana is described, followed by tests related to subsidy renewal in Indiana and Oklahoma. (author abstract)
