Drawing from work on the meta-analysis of over 500 validation studies of the General Aptitude Test Battery (GATB) by the U.S. Employment Service, the paper presents a methodological message and a substantive message. Gene Glass's methods, as used by Edwin Ghiselli in personnel selection, ignore study artifacts (sampling error, error of…

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…

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…

The United States Employment Service is now able to expand the General Aptitude Test Battery (GATB) coverage from approximately 400 jobs to all candidates for every job in the Dictionary of Occupational Titles (over 12,000 occupations).

The structure of this report is as follows: First, specific aptitude theory and general ability theory, the two theories of the relation between ability and job performance, are presented and differentiated. Second, there is a discussion of problems in the current use of the General Aptitude Test Battery (GATB) and of problems in the use of…

The issue of interpretation of standard test scores of minorities is discussed. The history of the issue is reviewed. The National Academy of Science's decision to reinterpret the scores of minorities is summarized. (YP)

This report cumulates the results of 515 validation studies carried out over a 45-year period by the United States Employment Service, and relates these findings to five systems of job classification and job analysis. Correction for sampling error shows that general cognitive, perceptual, and psychomotor ability are valid predictors of job…
