TO ESTABLISH A FRAME OF REFERENCE FOR THE BRITISH AUDIENCE, THE AUTHOR BRIEFLY DESCRIBES THE DIRECTOR OF ELECTRICAL AND MECHANICAL ENGINEER'S STUDY PERIOD (1965) AT ARBORFIELD, ENGLAND, THE MISSION OF THE HUMAN RESOURCES RESEARCH OFFICE (HUMRRO) IN ARMY RESEARCH AND DEVELOPMENT, THE U.S. ARMY PERSONNEL AND MAINTENANCE SYSTEMS, AND A PROCEDURE FOR CURRICULAR CONTROL. THIS PAPER IS LARGELY DEVOTED TO SELECTED EXAMPLES--FORECAST, JOBTRAIN, LIMIT, REPAIR, MOSAIC, AND MAINTRAIN--OF HUMRRO RESEARCH TASKS IN ELECTRONICS MAINTENANCE TRAINING. FINDINGS INDICATE THAT THE JOB IN THE FIELD MUST BECOME PARAMOUNT IN DETERMINING THE TRAINER'S PERSPECTIVE TOWARD TRAINING AND THE USE OF TRAINING MANUALS, AND THAT THE RESEARCH-DERIVED SYSTEMATIC MODEL FOR DEVELOPING TRAINING COURSES CAN BE USED WITH MARKED PROFIT.
