Childhelp.org reports that every year more than 3 million reports of child abuse are made in the US involving more than 6 million children (a report may include multiple children). The US has one of the worst records in child maltreatment among industrialized nations. Child abuse expert witnesses are effective advocates for children and may advise regarding child abuse and neglect, psychological mistreatment of a child, child maltreatment, and child sexual abuse.
The American Professional Society on the Abuse of Children explains:
The child forensic interview is the neutral fact-finding investigative interview conducted in child abuse and other cases in which violence is witnessed. There are several national and state training models that provide information and training on how to conduct these interviews. Professional certification is akin to licensing. Both are based primarily on rigorous psychometric testing and other empirically supported eligibility requirements.
