The Effect of Age, Education, and Work Experience on General Aptitude Test Battery Validity and Test Scores. USES Test Research Report No. 50.
Swarthout, David; Synk, David J.
Meta-analytic techniques were used to analyze the effects of age, education, and work experience on General Aptitude Test Battery (GATB) validities and test scores. The sample consisted of 30,568 subjects from 143 Specific Aptitude Test Battery (SATB) validation or revalidation studies analyzed since 1972. The effect of these three variables on GATB validities was investigated using the 24,219 sample members for whom the Standard Descriptive Rating Scale information was available. The sample was divided into intervals based on age, education, and work experience and the validities within the intervals were compared. Partial correlations were used to determine the effect of each variable on GATB validities. There were slightly more significant differences between validities for all jobs than would be expected by chance. Controlling for age somewhat increased validities. Education showed positive correlations with all nine GATB aptitudes, with the highest correlation for cognitive aptitudes and lower correlations for psychomotor aptitudes. Validities were higher for subjects with more than 12 years of education. When education was controlled for, validities decreased slightly. There were more differences in validities between experience levels than would be expected by chance, but the pattern was not consistent across the nine aptitudes. When experience was controlled for, validities increased slightly. Fourteen tables present data and nine graphs illustrate the text. An appendix gives tabulated information about the occupations of the subjects. (SLD)
