This study used meta-analysis research techniques to determine if there are differences in General Aptitude Test Battery (GATB) validities and test scores between males and females. The sample consisted of 26,111 subjects from 122 Specific Aptitude Test Battery (SATB) validation or revalidation studies analyzed since 1972. Four approaches were used to analyze the differences in validities between males and females. The first approach used the chi-square. Neither the cumulative chi-square nor the number of significant chi-squares showed significant differences between males and females. The second approach compared average differences in validities weighted by sample size. The average difference was .029 correlation points. The third approach compared average validities weighted by sample size. The largest difference was .05 correlation points. The fourth approach compared job family validities and showed no significant differences. The overall conclusion of this study is that there are no meaningful differences in GATB validities between males and females. Mean score differences were also analyzed. Males scored significantly higher on General Learning Ability, Numerical Aptitude, and Spatial Aptitude. Females scored significantly higher on Form Perception, Clerical Perception, Motor Coordination, and Finger Dexterity. There were no significant differences on Verbal Aptitude and Manual Dexterity.
