The Navy computer-managed instruction system (Navy CMI) is a large, multi-site operation. Research findings show that it is yielding benefits in terms of cost savings. During fiscal year 1975, savings of over ten million dollars were realized, mostly due to course reductions ranging from 24 to 80 percent and reductions in on-board students. It has been found that CMI training yields better end-of-course performance levels while maintaining more positive attitudes among students. Attrition rates are lower with CMI, and a continuation of this trend is predicted as the system is expanded. Savings are projected in the potential for expanded capability and competitive procurement using the current system and hardware. Research has shown positive personnel attitudes associated with the integration of personnel and operational procedures using CMI. It is suggested that performance and cost benefits qualify Navy CMI for expansion. (Author/CH)
