Abstract:

Historically, the Air Force has used technical school grades TSGs to validate aptitude tests. The purpose of the current study was to develop a job-related criterion metric against which to validate aptitude measures. Along this line, three Criterion Tests relevant to the 3, 5, and 7 skill level of PAFSC 426X2-jet engine mechanic-were developed. ANOVA results demonstrated that mean Criterion Test scores were significantly different across the relevant skill levels. Stepwise regression results indicated that Armed Services Vocational Aptitude Battery ASVAB information subscales were most predictive of Criterion Test performance for experienced mechanics. Considering only basic airmen, the ASVAB information measures and general knowledge subscales were most related to Criterion Test performance. When TSGs were regressed on ASVAB scores, general knowledge scales were most consistently predictive of technical school performance. The regression of TSGs on Criterion Test scores indicated that only Test I was generally related to technical school performance. Author
