Past studies have indicated that job performance in general tends not to decline with age, but performance on at least several aptitudes does decline noticeably with age. If these relationships hold up over the entire occupational range, there is the possibility that aptitude correlations with job performance may be moderated by age. To…

Test-retest reliability coefficients for the brief Career Ability Placement Survey and concurrent validity correlations against the Differential Aptitude Tests and the General Aptitude Test Battery are presented for samples of ninth and tenth grade students. (Author/JKS)

Three multiple-abilities batteries--the Comprehensive Ability Battery, Differential Aptitude Tests, and General Aptitude Test Battery--are briefly discussed, and results of a study involving cross-correlations of the tests in these batteries are presented. (Author/JKS)

Comparative validity data for the Career Ability Placement Survey and the General Aptitude Test Battery relative to predicting course marks are presented for a sample of ninth grade students. The pattern of correlations between school grades and conceptually similar tests in the two measures was highly similar. (Author/JKS)

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…
