Validity of tests for auto mechanics

Abstract

The purpose of this study was to test the notion that tests of arithmetic, spatial relations, and mechanical principles would be useful in predicting the actual job success of automotive maintenance employees. 225 bus maintenance and repairmen were the subjects; the criteria were ratings by foremen and superintendents. The correlations between the test scores and ratings were: Arithmetic, r = .19; Spatial Relations, r = .21; Mechanical Principles, r = .30. (PsycInfo Database Record (c) 2025 APA, all rights reserved)
