The document presents the results of a preliminary study on the development of job performance aids. Job performance aids are information devices which are applied in actual work situations to assist the worker in the performance of his task. The uses and advantages of job performance aids for the training of Navy personnel are discussed. In order to establish methods of job performance aid development that will have general application, the study developed a categorization of job aid devices based on data collected from a questionnaire designed to gather information on existing attitudes and practices. A set of conversion cards for aiding Commissarymen in recipe conversion was also constructed to determine the feasibility of applying job performance aids to nontechnical ratings. A list of references is included. The survey questionnaire on current practices of job aid implementation and the recipe conversion job aids are appended. (Author/EC)
