Walk-Through Performance Testing: An Innovative Approach to Work Sample Testing

摘要

Work sample tests have been advocated as reliable, valid measures of job proficiency. Work sample procedures normally identify critical tasks, discard those tasks not practically observable and measure the remainder with hands-on tests. For the Air Force, hands-on testing is a particular problem because of the complexity and expense involved in performing many tasks. Walk-Through Performance Testing (WTPT) is being developed to expand the range of job tasks measured, to include tasks that do not lend themselves to hands-on testing. WTPT is a task-level job performance measurement system which combines hands-on task performance and interview testing procedures to provide a high-fidelity measure of an individual's technical job competency. The addition of an interview testing component allows the test administrator to evaluate by means of a show-and-tell procedure individual competencies on tasks not measurable by the hands-on process. This technical paper details the background, theoretical basis, and development procedures involved in WTPT.
