Dynamic Inspection Aptitude Test (DIAT): A Measure of Aptitudes Required for Nondestructive Testing

摘要

The Dynamic Inspection Aptitude Test (DIAT) was developed to predict operator success in the application of nondestructive testing methods that require the combined aptitudes of general cognitive ability, abstract reasoning, and spatial visualization. The test is computer administered and scored, requiring 36 minutes of testing time. Validation studies showed that the test was highly reliable, correlated with other measures of these key aptitudes, and was predictive of the job performance of ultrasonic nondestructive testing operators. These results indicated that the DIAT can be used with confidence for the early identification of individuals who will benefit most from training and experience on ultrasonic nondestructive testing tasks, and who will be most likely to meet operator qualification standards.
