The main purpose of this legislation is to strengthen efforts to combat fraud in federal programs, particularly in child care, health care, and other areas. It aims to ensure that taxpayer money is used properly and that fraudulent activities are minimized. Key provisions of the legislation include several measures aimed at preventing fraud in child care services. States are required to base payments to child care providers on actual attendance rather than just enrollment. This means that providers will only receive payment for the days that children actually attend.
