The main purpose of the Air Force project was to develop a universal model to evaluate usage of basic electronic principles training. The criterion used by the model to evaluate electronic theory training is a determination of the usefulness of the training vis-a-vis the performance of assigned tasks in the various electronic career fields. Data collection is through a survey booklet, called the Electronic Principles Inventory, which is completed by practitioners in the field. The inventory is general in nature and can be administered to anyone who works with electronics, regardless of the level of involvement. The data can be analyzed using the Comprehensive Occupational Data Analysis Programs (CODAP). Significant results were found between and within electronic specialties. The results presented in the report would be useful to managers in the areas of training, personnel classification, and testing. (Author/EA)
