Application background checks provide another link in the chain. The guards' primary duties are to observe, report, and deter violations of the law, university policies, and dormitory policies. The training program consists of two sessions, one for both experienced and inexperienced guards, and the second only for new guards. The most important aspect of the training program is its coverage of the decision-making and confrontation processes. This training enables night guards to adapt to the many situations that could arise in the dormitories. As part of the training system design, standards of performance are established and used in the program. Some of these duties include locking doors and setting up stations, verifying identification of each person who enters the building. Other duties include making rounds 50 minutes of each hour, accurately observing and reporting all relevant details, and approaching each violator. Barriers to night- guard training may include the inability of guards to see a "payoff" for doing a good job, lack of motivation to perform every specified task, failure to remember procedures that are not often used, and lack of on-the-job supervision. Several techniques have been developed to overcome these problems and ease transference of training.
