The program is intended to interrupt the evolution of juvenile to adult criminal careers among SHO/DI youth. The operational model describes each of the program tasks, the procedures required for each task, and the outcomes that can be expected. The first task is the establishment of a juvenile data base through review of police files and other juvenile records. Criteria then are established for identifying the SHO/DI population, usually through an analysis of offense frequency distribution and seriousness. Police, acting with other juvenile agencies then can develop processes for early identification and procedures for specialized crime analysis functions. Program implementation also requires the establishment of police internal and interagency linkages for information flow and the development of specialized procedures for dealing with SHO/DI youth. Interagency and community support should then be pursued, and a focus should be placed on organization development and the provision of intraagency and interagency technical assistance.
