The Purdue Industrial Training Classification Test

Abstract

To measure the validity of this test (see 16 : 4979), the scores of 279 trainees in three vocational programs were compared with teachers' ratings of probable vocational success. When the trainees are grouped according to ratings into low fourth, middle half, and high fourth, mean test scores are found to increase regularly; for two groups the differences between extreme fourths are statistically significant. Percentile norms are presented for seven different groups of male subjects, with N's varying from 82 to 811. (PsycInfo Database Record (c) 2025 APA, all rights reserved)
