Selected individuals must possess the physical ability to successfully complete the practical self-defense exam, which involves the following: lift arms above head and kick as high as own waist; stabilize another person to accomplish a controlled take down; use arms, palms of hands, shins, and feet to deliver blows; withstand impact (slow speed or with a safety bag) on own body from strikes/blows; rotate body 90 degrees with feet planted for striking with foot or using a defensive tactic; get down on one or both knees and up again with multiple repetitions. Supervision is exercising span and control over subordinate staff to include coaching, mentoring, daily monitoring, performance management (planning, reviewing, and evaluating), resolving complaints/grievances, responsibility for scheduling and leave approval, and providing input that could affect pay, status, or tenure.
