Two rating instruments for evaluating the performance of men in Navy jobs by supervisors were developed based on the need to know how effectively men of varying ability perform different tasks. Specific Navy jobs were selected for the development of the performance instruments according to the following job factors: Highly populated, representation of different job characteristics, likelihood of common tasks across billets, representation of low aptitudes, and availability of Navy Occupational Task Analysis Program (NOTAP) data. The resulting two instruments developed were the Performance Analysis Inventory (PAI) and the Task Proficiency Inventory (TPI). The PAI analyzes performance in terms of worker-oriented variables and is based upon job analyses using a modification of McCormick's "Position Analysis Questionnaire." The TPI analyzes performance in terms of job-oriented variables and is based upon job analyses conducted by the Navy Occupational Task Analysis Program. Within the limitations of a comparison of experimental and operational data, both the PAI and TPI show less leniency and halo effects, and better discrimination than the Performance Evaluation Report used in the Navy. Both experimental instruments will be used in subsequent research on the performance of men in different mental categories. (Author/HD)
