This paper describes a process used to evaluate various types of media used in a training organization. The process uses as its basis a training device selection model that incorporates concepts of training effectiveness, technical efficiency and cost into an algorithm in order to determine the most effective training device(s) to be utilized in a training situation. This algorithm uses weighted scores as a basis for determining an optimal rank ordering in the three categories of training effectiveness, technical efficiency and cost. The final determination of which media are the most effective in training students is made by the analysis team utilizing data provided by the model. This paper provides a description of how the process was used by the analysis team in evaluating the training situation at the Marine Corps Security Force Battalion.
