The CCDBG Act of 2014 also included a provision for GAO to review every 2 years the number of families eligible to receive assistance under the CCDBG Act of 1990, as amended, as well as those who have applied for assistance and those who have been placed on a wait list for assistance. To address this provision, this report describes (1) what is known from the most recent data available from HHS about the extent to which eligible children received child care subsidies and their characteristics, and (2) how states plan to use the increase in CCDF funding from the Consolidated Appropriations Act, 2018, including addressing wait lists. The report includes the slides we used to brief your staff in October 2018 (see enclosure I). HHS since updated its data on subsidy receipt in January 2019, and this letter reflects the updated data.
