In 2000, the California Legislature passed the Schiff-Cardenas Crime Prevention Act, which authorized funding for county juvenile justice programs and designated the Board of Corrections (BOC) as the administrator of funding. A 2001 Senate Bill extended the funding and changed the program's name to the Juvenile Justice Crime Prevention Act (JJCPA). This effort was designed to provide a stable funding source to counties for juvenile programs that have been proven effective in curbing crime among at-risk and young offenders. The Board is required to submit annual reports to the California legislature measuring the success of JJCPA. The legislation identified six specific outcome measures to be included in annual reports from each of the individual JJCPA programs. These outcomes include successful completion of probation, arrests, probation violations, incarcerations, successful completion of restitution, and successful completion of community service. Each county can also supply supplemental outcomes to measure locally identified service needs. The RAND Corporation was funded by the Los Angeles County Probation Department to conduct the evaluation of the County's JJCPA programs, including analyzing and reporting findings to the BOC. This report contains a summary of the fiscal year 2003-2004 (FY 03-04) findings reported to the BOC, as well as additional program information gathered by Los Angeles County Probation based on its oversight and monitoring of program implementation and outcomes. (Seven appendixes are included: (1) Description of Comparison Groups for JJCPA Programs; (2) Probation's Ranking of the "Big Six" Outcome Measures; (3) Community-Based Organizations (CBOs) That Provided Services for JJCPA Programs in FY 03-04; (4) BOC-Mandated and Supplemental Outcomes for Individual JJCPA Programs, FY 03-04; (5) Additional Statistics for Selected Programs; (6) Selected Outcomes, by type of JJCPA Program; and (7) BOC-Mandated and Supplemental Outcomes, by Cluster, for Selected Programs. Contains 11 footnotes and 37 tables.) [This report was written with Jitahadi Imara, Davida Davies, and Apryl Harris. For associated summary, see ED502786.]
