This report is the fourth in a series of Wisconsin Council on Children and Families (WCCF) reports tracking the progress of Wisconsin's YoungStar program, a quality rating and improvement system (QRIS) launched in 2011 to improve the quality of Wisconsin child care programs. YoungStar focuses on children of low-income working families receiving assistance from the Wisconsin Shares child care subsidy programs. YoungStar rates the quality of child care programs on a 5-Star scale and is administered in 6 regions of the state. The analysis in this report is based on data as of the end of July 2013. Programs are rated 1-Star if they do not meet health and safety standards, and are prohibited from receiving Wisconsin Shares funding. Two-Star programs meet basic regulatory standards for health, safety, program, and personnel (prior to 2011, these were the only standards required to participate in Wisconsin Shares). Star levels 3, 4, and 5 represent progressively improved quality, with an emphasis on early learning and development. For more background on YoungStar, the quality indicators, and a summary of the program's implementation history, see the Appendix at the end of this report.
