Reliability of Mechanical Maintenance Performance Measures
Abstract
A fundamental requirement in the development and administration of performance measures is that such assessments should result in reliable scores that accurately indicate a person's level of proficiency. This research memorandum examines the reliability of two performance measures of mechanical maintenance developed for the Marine Corps Job Performance Measurement Project: hands-on performance tests and job knowledge tests. Multiple estimates of reliability were computed, and the consistency of test administrators in scoring hands-on performance was specifically examined. The hands-on performance tests and the job knowledge tests were found to result in very reliable measurements. Properly trained and monitored test administrators were able to score hands-on performance consistently across examinees, over time, and for different test content. Implications for subsequent performance measurement are presented, and possible training implications based on mechanics who were retested are noted.
