The Child Abuse Prevention and Treatment Act, as amended (42 U.S.C. 5106a), requires States to make provision for the cooperation of State law enforcement officials and State agencies providing human services in the investigation, assessment, prosecution, and treatment of child abuse or neglect. All 50 States, the District of Columbia, and the U.S. territories have statutes specifying procedures that State agencies must follow in handling reports of suspected child abuse or neglect. In most States, these procedures include requirements for cross-system reporting and/or information sharing among professional entities. Typically, reports are shared among social services agencies, law enforcement departments, and prosecutors' offices.
