This report contains the recommendations adopted by the National Advisory Committee on Juvenile Justice and Delinquency Prevention, 1979. Proposed standards and strategies are presented in the first five chapters. Each standard is followed by a source list and an explanatory commentary about its underlying premises and its relationship to other recommendations. Consistent and conflicting positions from other authorities are included, and specific recommendations for implementation are offered. The chapter on Prevention Function includes a definition of delinquency prevention and 37 prevention strategies. The Administration Function chapter contains standards on the role of local, state, and federal government levels in the juvenile service system; the Intervention Function chapter provides criteria and guidelines for intervention by public officials. The Adjudication Function chapter recommends the establishment of a family court; the Supervision Function chapter is directed to agencies supervising juveniles and families subject to the jurisdiction of the family court. The sixth chapter presents a general implementation plan outlining criteria for assessing the various available implementation mechanisms, and two implementation strategies which appear to meet those criteria.
