Primary intended users of this second volume of a two-volume handbook are professional counselors and placement officers involved in expanding the range of jobs available to persons having only basic cognitive skills (e.g., mentally retarded, slow learners, learning disabled). Summary job requirements information is presented for more than 8,000 occupations selected from the more than 14,000 occupations listed in the third edition of the "Dictionary of Occupational Titles" (DOT). The information is intended to support the counseling and placement actions suggested in volume 1. Each of the occupations included has been judged by analysts to have requirements not in excess of an eighth grade level of educational development. Each occupation has also been judged for the purpose of determining the level of mental processing required on inputs from sensory modes--sight, audition, touch/kinesthesis, taste, and smell. None are expected to require more than one year of specific vocational preparation. Many included have far less rigorous demands than these. Content is structured on the basis of DOT classification. Nine major occupational categories are included: (1) professional, technical, and managerial occupations, (2) clerical and sales, (3) service, (4) farming, fishing, forestry, and related, (5) processing, (6) machine trades, (7) bench work, (8) structural work, and (9) miscellaneous.
