42 U.S. Code § 13031 - Child abuse reporting
A person who, while engaged in a professional capacity or activity described in subsection (b) of this section on Federal land or in a federally operated (or contracted) facility, learns of facts that give reason to suspect that a child has suffered an incident of child abuse, shall as soon as possible make a report of the suspected abuse to the agency designated under subsection (d) of this section.
For all Federal lands and all federally operated (or contracted) facilities in which children are cared for or reside, the Attorney General shall designate an agency to receive and investigate the reports described in subsection (a) of this section. By formal written agreement, the designated agency may be a non-Federal agency. When such reports are received by social services or health care agencies, and involve allegations of sexual abuse, serious physical injury, or life-threatening neglect of a child, there shall be an immediate referral of the report to a law enforcement agency with authority to take emergency action to protect the child. All reports received shall be promptly investigated, and whenever appropriate, investigations shall be conducted jointly by social services and law enforcement personnel, with a view toward avoiding unnecessary multiple interviews with the child.
In every federally operated (or contracted) facility, and on all Federal lands, a standard written reporting form, with instructions, shall be disseminated to all mandated reporter groups. Use of the form shall be encouraged, but its use shall not take the place of the immediate making of oral reports, telephonically or otherwise, when circumstances dictate.
All persons who, acting in good faith, make a report by subsection (a) of this section, or otherwise provide information or assistance in connection with a report, investigation, or legal intervention pursuant to a report, shall be immune from civil and criminal liability arising out of such actions. There shall be a presumption that any such persons acted in good faith. If a person is sued because of the person’s performance of one of the above functions, and the defendant prevails in the litigation, the court may order that the plaintiff pay the defendant’s legal expenses. Immunity shall not be accorded to persons acting in bad faith.
All individuals in the occupations listed in subsection (b)(1) of this section who work on Federal lands, or are employed in federally operated (or contracted) facilities, shall receive periodic training in the obligation to report, as well as in the identification of abused and neglected children.
