Work Unit REALISTIC was undertaken by the Human Resources Research Organization to provide information concerning demands for reading, listening, and arithmetic skills in selected military occupational specialties and to provide information relevant to the matching of personnel literacy skills to job demands for such skils. This report describes results of research on (1) the relationship between the literacy skills of men in the military occupational specialties and their job proficiency, (2) the reading difficulty level of job printed materials and the extent of usage of these materials by men of different reading ability levels, (3) the extent to which men of differing reading ability levels ask questions of and listen for job information, and (4) the extent and nature of use of arithmetic by men of differing reading ability levels. Methods are discussed to reduce gaps between personnel literacy skill levels and the literacy demands of the jobs through job-oriented remedial literacy training or by redesigning the job literacy materials. Since reading ability was found to be most highly related to job proficiency, it is suggested that diagnostic, skill-oriented instruments be used for screening purposes. Tables, figures, references, and appendixes are included. (AW)
