In a time of declining budgets and increased public transparency, criminal justice agencies are increasingly relying on evidence-based programs (EBP) to handle recurring issues. This dissertation examines the success of the Hermiston Police (OR) Community Accountability Board (CAB) and its effects on juvenile recidivism (2009-2012). Utilizing a mixed-method approach, this study incorporates a traditional program hierarchical design. Throughout this study, research questions measure the program’s effectiveness. The study focuses on the Needs Assessment followed by assessments of the Program Design and Theory, Program Process and Implementation, Program Outcome/Output, and Program Cost and Efficiency. Utilizing elements of Control Theory and Restorative Theory the study compares recidivism rates between the city of Hermiston, the County of Umatilla, and the State of Oregon. A quasi-scientific test is used to compare the experimental group that attended the CAB (N = 220) during 2009-2012 and all the other juvenile arrests throughout the City of Hermiston. Through collaboration with the Hermiston School District and the UCCJ-YSD (juvenile department), this study uses bi-variate and multi-variate tests to determine relationships between completion rates, success rates, and arrest rates of juveniles to the effects of race, parental support, and timeliness of program implementation. Participants were identified as Caucasian and Non-Caucasian to avoid unintentional identification of participants due to small numbers of minority races. In addition, the study excluded those above 18 years of age or below 10 years of age to focus on the core group that the CAB was designed to effect only. In addition, the efficiency of the program was revealed through a ratio analysis between the cost of juvenile crime, in the Hermiston area, and the costs of the program. The study revealed that though there were implementation problems and a lack of a firm program theory, the program was effective at reducing juvenile recidivism and was efficient in doing so. Although it appears that efficiency is dropping due to fewer participants in the CAB, this study revealed an excellent opportunity for collaborative programs and an adjustment in the implementation of the CAB that has the potential to continue reducing juvenile offenses below the state average.
