摘要

A proficiency test was constructed to evaluate performance of Naval technicians maintaining the AN/SKQ-1 telemetering ground station equip¬ment. 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.nThe job sample performance test approach was selected after an analysis of the relative merits of testing approaches in achieving an optimal balance between psychometric principles and practical aspects of test use. Job task data were collected from several fleet sources and from a Navy school and were analyzed to identify task requirements imposed on the fleet technician.nA 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.nSampling effectiveness was treated as a function of the degree of representation and the amount of redundancy incurred to achieve that 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.nDuring test construction, certain practical limitations of the performance test approach were dealt with by setting up a series of guidelines based on performance test characteristics that fleet supervisors and school instructors felt were acceptable. Design of the test was made consistent with those guidelines with the hope of assuring practical accept¬ance of the test in the field. Throughout test construction, effort was made to obtain a sequence of maintenance events that were compatible with the natural flow of events in the tactical environment. Also, every attempt was made to simplify the observer-scorers job.nEvaluation and veritifcation of the job-task data, the task sample, and the accuracy of test components were performed using experienced fleet personnel, equipment field engineers and school instructors. Problems constructed to tap examinee fault isolation behavior were evaluated on the equipment as specified and equipment responses and fault isolation procedures were verified.nThe test is composed of two major sections that require a total administration time of slightly over three hours. To conform with Navy fleet supervisors and school instructor desires, the test was designed so that each section could be interrupted at a particular point. That feature should provide for flexibility in integrating test administration into finite amounts of test time available.nSince the AN/SKQ-1 equipment is still in the process of fleet integration and shake-down, it is recommended that the development of the system in the fleet be monitored so that any modifications in hardware or procedures can be detected and their effect on test accuracy appraised immediately.
