Which agency is responsible for reporting suspected child abuse or neglect?

Child protective services (CPS) is the agency specifically mandated to investigate reports of suspected child abuse or neglect. CPS operates at the state or local level, and its primary function is to ensure the safety and well-being of children. When there are allegations or suspicions of abuse or neglect, it is CPS that conducts the assessments and initiates interventions if necessary, such as placing the child in a safe environment or providing services to families.

While the other options mentioned (Department of Social Services, Child Welfare Agency, Family Services Department) may also be involved in broader child welfare issues or provide supportive services, they do not exclusively focus on the direct investigation and intervention activities associated with suspected abuse or neglect. CPS is distinct in that its sole responsibility revolves around child protection and responding to these critical situations, thus making it the correct choice in this context.
