AN INVESTIGATION WAS CONDUCTED TO DETERMINE THE FEASIBILITY OF PROVIDING NAVY CLASS A COMMISSARYMAN SCHOOL TRAINING FOR MENTAL GROUP IV PERSONNEL. THE ACHIEVEMENT OF 17 GROUP IVS WAS COMPARED WITH THAT OF 29 REGULAR STUDENTS IN TWO SUCCESSIVE EIGHT-WEEK CLASSES OF THE COMMISSARYMAN SCHOOL. RESEARCH DATA WERE OBTAINED FROM SERVICE RECORDS, PRETRAINING AND COURSE ACHIEVEMENT TESTS, PRETRAINING AND POSTTRAINING QUESTIONNAIRES, AND INTERVIEWS WITH INSTRUCTORS. THE GROUP IV PERSONNEL SUCCESSFULLY COMPLETED THE COMMISSARYMAN TRAINING. HOWEVER, THEIR COURSE ACHIEVEMENT, AS MEASURED BY TYPICAL SCHOOL TESTS, TENDED TO BE SIGNIFICANTLY LESS THAN THAT OF REGULAR STUDENTS IN THE SAME CLASSES. SPECIFIC PROBLEM AREAS WERE IDENTIFIED, AND THE APPROPRIATENESS OF CERTAIN JOB AIDS AND TRAINING MODIFICATIONS WAS DISCUSSED. RECOMMENDATIONS WERE MADE FOR THE TRAINING OF GROUP IV PERSONNEL AND FOR FURTHER RELATED RESEARCH.
