The Child Care and Development Block Grant Act (CCDBG Act) of 2014 added new requirements for States that receive funding from the Child Care and Development Fund (CCDF) to conduct comprehensive criminal background checks on staff members and prospective staff members of child care providers every 5 years. Criminal background check requirements apply to any staff member who is employed by a child care provider for compensation or whose activities involve the care or supervision of children or unsupervised access to children. Our objective was to determine whether the District of Columbia’s monitoring process ensured provider compliance with District requirements related to criminal background checks established under the CCDBG Act.
