This Report to Congress is required by Section 658L of the Child Care and Development Block Grant (CCDBG) Act as amended. The report provides information about the role of the Child Care and Development Fund (CCDF), which is authorized under the CCDBG Act, in improving access to high-quality child care in states, territories, and tribes. This report covers fiscal years 2014 and 2015. While the program's authorizing statute was reauthorized during this period, the law had not yet been implemented in many states. The data and analysis contained in this report are from a variety of sources, including administrative data about children and families receiving CCDF services. Some data was not yet available at the time this report was drafted in accordance with the statutory submission deadline, but that data will be posted online. This report includes highlights of CCDF program activities, information on activities states and territories are doing to improve the quality of child care across the country, and an overview of the Administration for Children and Families' Technical Assistance and Research projects. The report closes with a look to the future. [For "Child Care and Development Fund (CCDF). Report to Congress for FY 2012-FY 2013," see ED591073.]
