This article reports the findings of an evaluation of a juvenile justice system diversion project which took place in Orange County, California during the years between 1971 and 1975. The evaluators' findings suggest that the project was an effective supplement to the existing traditional system. During the period of project demonstration, four of the five members of the County Board of Supervisors were replaced. The new decision makers elected to discontinue the project. It is suggested that improved management of the evaluation would have enhanced the utility of the evaluation for the key county decision makers.
