A proficiency test was constructed to evaluated performance of Naval technicians maintaining the AN/SKQ-1 telemetering ground station equipment. The test is to be used for evaluating the preparedness of Navy school graduates for fulfilling the requirements of their fleet jobs and to provide diagnostic feedback to curriculum evaluation appraisal efforts. Job task data were collected from several fleet sources and from Navy school and were analyzed to identify task requirements imposed on the fleet technician. A sampling plan was developed based on a mission contribution criterion. Tasks were then ordered on a continuum of contribution to mission success and activity statements were developed to provide a means for investigating task interrelations and for use in determining sampling effectiveness. Several sampling guides related to mission contribution, scope of task, skill level required and use of test support equipment were developed to facilitate the mechanics of the sampling process. Sampling effectiveness was treated as a function of the degree of representation and the amount of redundancy incurred to achieve hat level. An index of representation and an index of uniqueness were defined to provide a quantitative means for describing the effectiveness of a given sampling configuration. A third index was employed to determine overall sampling effectiveness for the task sample according to sampling plan criteria and for the total job. (Author)
