This bulletin reports results from an evaluation of six sites of the Safe Kids/Safe Streets (SK/SS) program, which applies a comprehensive, collaborative approach to the child maltreatment field. The bulletin provides insights into collaboration building, systems reform, service options, and other strategies. Among the findings were that the SK/SS communities made impressive progress both in establishing effective collaboratives and in implementing plans to improve local systems and services. In addition to improving services, all sites made significant organizational changes, improving multidisciplinary teaming through children's advocacy centers (CACs); setting up specialized law enforcement, prosecution, or court units; and adopting new protocols and procedures. Among the lessons learned from the SK/SS experience were that its approach can succeed in a wide range of communities and that its flexible program design and oversight help programs overcome barriers and adapt to new challenges and opportunities. While collaborative approaches have been successfully used elsewhere, the SK/SS initiative represents the most comprehensive application in the child maltreatment field.
