Levine, E. L., Spector, P. E., Menon, S., & Narayanan, L. (1996). Validity generalization for cognitive, psychomotor, and perceptual tests for craft jobs in the utility industry. Human Performance, 9, 1-22. Abstract

Examined the generalizability of several test types for a sample of craft jobs in the utility industry, ranging from very complex skilled jobs to jobs that were unskilled. The predictors (test categories) were cognitive, perceptual, and psychomotor tes ts. A meta-analytic method developed by Raju et al. assessed the extent of validity generalization. 80 studies representing 167 samples were used. Data support the validity of the 3 different types of tests for use in selecting among job types similar to those studied. Cognitive tests exhibited a pattern of results supportive of the position that they are valid across many job types. Psychomotor tests, and to some degree perceptual tests, also offered useful levels of validity for less technical jobs (Copyright 1996, Lawrence, Erlbaum Associates.)
