Child Abuse Prevention And Treatment Act (CAPTA)
The law (P.L. 93-247) that provides a foundation for a national definition of child abuse and neglect. Reauthorized in October 1996 (P.L. 104-235), it was up for reauthorization at the time of publication. CAPTA defines child abuse and neglect as "at a minimum, any recent act or failure to act on the part of a parent or caretaker, which results in death, serious physical or emotional harm, sexual abuse or exploitation, or an act or failure to act which presents an imminent risk of serious harm."
