Four levels of supervision were delineated: maximum, medium, minimum, and limited. Levels are determined on the basis of risk/needs scores. To develop and implement a more equitable system of case assignment, a study was conducted in 1984 to compile a list of officer activities, examine officer leave, and consider alternative case assignment techniques. Time studies of 40 percent of all supervision officers and of 30 percent of all cases at each supervision level also were conducted. These data provided the information necessary to base case assignment on a workload development system wherein assignments are determined by the officer's total workload points as compared to those of other officers and the new client's risk/need score. The workload concept has shown itself to be a credible tool in the budget process and in the reallocation of existing resources. Since the initial study, a new study has been conducted to validate and update the statistics. 5 footnotes.
