WestEd’s Justice and Prevention Research Center (JPRC) led an evaluation of training provided to investigators assigned to the Internet Crimes Against Children Task Force Program (ICAC). This project was funded by the Office of Juvenile Justice & Delinquency Prevention, and later overseen by the National Institute of Justice. ICAC coordinates a network of task forces that help law enforcement agencies nationwide investigate and prosecute crimes involving children, particularly crimes of sexual exploitation. ICAC supports include forensic and investigative components, training and technical assistance, victim services, and community education. The National Evaluation of ICAC Task Force Training assessed the quality, implementation fidelity, and outcomes associated with OJJDP-funded ICAC training.
