An Evaluation of the IPI-Inspection Test

Abstract

The Color Video Comparator (CVC), a semiautomated inspection device was used to assess the validity of a commercially available selection test for inspectors published by Industrial Psychology, Inc. (IPI). The IPI battery included five aptitude subtests (Blocks, Dimensions, Tools, Precision, and Parts). Factor analysis was performed to determine the underlying factor patterns measured by the IPI-inspection tests. Also, Pearson correlations were performed to evaluate the strength of associations between IPI-inspection tests scores and different inspection performance measures. The results, in general, suggested that the IPI-inspection tests which measure multiple attributes demonstrate a predictive ability for many performance measures of the CVC inspection task.
