The Mastery Learning Project at the Marine Corps Communication-Electronics School in Twentynine Palms, California is the Marine Corps' test bed for the development of a self-paced, mastery-learning strategy. This strategy is viewed as the way to improve personnel and training readiness by providing complex technical instruction in less time, with less academic attrition, and with no degradation in quality. The key to success lies in the emphasis placed on offering closer, more personalized instructor attention to those students who require it. A computer-based management information system provides essential automated support for instructional personnel as well as for all the administrative and managerial functions within the school, thereby permitting substantial reductions in training overhead costs. Experience gained thus far has shown that students are achieving mastery of all learning objectives in 70% of the conventional training time, with academic attrition approaching zero.
