Three police training programs varied markedly and present a selection of models appropriate to different circumstances and training needs. The New Jersey Police Training Commission provides for supervisory training through the use of mobile classrooms staffed with trained professional teams, equipped with modern teaching aids, and experimenting with programed as well as traditional materials. In the first year, 717 officers participated in 28 four-day courses at 17 separate locations throughout the state. The North Carolina Police Management Institute provided a split-session, one-month management course for 26 municipal police officers. In five 4-day sessions spread over a six-month period, 120 hours of instruction were given. This provided for outside reading and problem-solving assignments on the back-home situation. The Arkansas Law Enforcement Academy developed a new training program at the basic supervisory level. A total of 386 trainees attended the four-course series (3-5 days duration per course) conducted in each of five regional locations across the state. This was phased over a seven-month period with classes scheduled on working days and ending in time for the men to return home each day. (NL)
