A procedure for estimating the degree to which a subtest uniquely contributes to total test performance is presented and discussed. Uniqueness analysis may be appropriately applied to any composite measurement instrument such as a multipart test or a multitest battery to assess the unique contribution of each component to the total test. The…

Variables that correlate with scores on the National Certifying Examination (NCE) for Physician's Assistants (PAs) were investigated. It is noted that NCE scores represent professional entry-level performance for PAs and that identification of variables related to PA performance may promote the development of standardized selection criteria. The…

Meta-analysis techniques were used to determine whether or not there are differences in General Aptitude Test Battery (GATB) validity and test scores between samples from the Northern, Southern, and Western United States census areas. The sample consisted of 26,111 subjects from 122 validation studies of the Specific Aptitude Test Battery (SATB).…

The purpose of this investigation was to examine historical changes in aptitude scores. Recent literature suggesting a decline in the quality of the U.S. workforce is reviewed, and an expectation that score distributions on aptitude tests have shifted in a negative direction is presented. Archival analyses of normative data for the Short…

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…

The analyses of J. E. Hunter (1983) were replicated with an expanded data set. The Hunter study, the basis of the Validity Generalization system used by the United States Employment Service, contained 515 General Aptitude Test Battery validation studies. The data set in this study included these and additional studies to bring the data set to 755…

Describes the evolution of "race-norming," or "within-group scoring," the practice by which job candidates' scores on employment tests are reported relative to comparison groups of their own race or ethnicity. Contends that race-norming fosters group rather than individual rights and perpetuates the inequality it intends to…

The Armed Services Vocational Aptitude Battery (ASVAB), a battery of 10 vocational tests, was administered to a national probability sample of nearly 12,000 young people, 15 to 23 years of age. Score distributions from the study were needed by the Armed Services to set performance levels for accepting and assigning recruits. Three psychometric…

Six new forms of Armed Services Vocational Aptitude Battery (ASVAB) were developed. These new forms were equated to a standard reference test, ASVAB 8a, using normative data based on a 1980 weighted probability sample of American youth, ages 18-23. Equating allows the services to report the distributions of examinee ability on a common metric or…

The pertinent aspects of 22 approved tests are individually summarized. The test reviews are based on examinations of the test publishers' technical documentation and the tests. Information provided in the…
