This final report describes the program and evaluation efforts that took place in San Diego County for the "Breaking Cycles" project to address juvenile crime. This effort was funded by the State Legislature through the California Board of Corrections (BOC). Administered through the San Diego County Probation Department, this collaborative effort incorporates a two-pronged approach to prevent at-risk youth from entering the system and hold juvenile offenders accountable through a comprehensive system of graduated sanctions. To meet the evaluation requirements of the BOC, the Criminal Justice Research Division of SANDAG conducted aprocess and impact evaluation of the program.
