All 365 full-time probation and parole officer positions were sampled on randomly selected days. The increase in time spent on investigatory activities was attributed to the revised report format incorporating additional data elements and to policy changes requiring a formal report on all persons entering probation or parole supervision. Contributing factors in the decline of supervisory time were the redirection of time to investigatory activities and the shifting of cases to lower levels of supervision. Other assigned duties required more time, in part reflecting requirements in the standards instituted in May 1983. The standards mandate minimum training hours and periodic staff meetings. The use of leave time was relatively stable compared to 1983. Recommendations presented to the deputy director in March 1987 suggested further analysis of certain findings, a reduction in the number of supervisory levels, a revised workload measure for supervisory and investigatory services, and periodic re-evaluation of service priorities and their time requirements.
