The information matrix for the parameters in a latent-variable model is bounded from above by the information that would obtain if the values of the latent variables could also be observed. The difference is the "missing information." This paper discusses the structure of the information matrix, and characterizes the degree to which…

Univariate and multivariate corrections for range restriction were compared using scores of 147,288 Navy applicants on the Armed Services Vocational Aptitude Battery. Composite validities were corrected using the univariate and multivariate formulas. In general, multivariate corrections were more accurate than univariate corrections. This accuracy…

A sample of 9173 noninstitutionalized youth who took the 1980 Armed Services Vocational Aptitude Battery (ASVAB) was divided into five ability levels. Analysis supports the assertion that cognitive abilities are less correlated in higher ability groups and implies that greater classification effects can be associated with more intelligent groups.…

Recently there appears to have been an increase in interest in the relative power of general ability and narrower cognitive aptitudes to predict real world performance in training programs and on the job. This area has important practical implications for personnel selection and classification, particularly for large organizations such as the…

Predictability of graduation from the Community College of the Air Force was studied in a sample of 518 master sergeants. Armed Services Vocational Aptitude Battery (ASVAB) electronics scores and gender were significant predictors; age, ethnicity, major, and ASVAB mechanical, administrative, and general scores were not.

The project reported here consisted of a sensitivity review of the items of Forms 11, 12, and 13 of the Armed Services Vocational Aptitude Battery (ASVAB). Because administration of this battery is a required step in the accession process, it should be free from perceived bias or offensiveness that could detract from the measurement process. In…

This is the third report on the use of a technical classification assessment center (TCAC) for evaluating general detail (GENDET) personnel in the Navy. The first two reports described the development of the TCAC and the validation of the TCAC against supervisors' ratings of job performance for a small exploratory sample. This report presents the…

Armed Services Vocational Aptitude Battery (ASVAB) Form 2 was standardized for Digitek answer sheets. In September 1973, the Digitek scoring facility at Randolph AFB will be inadequate to handle anticipated scoring load. Consequently, ASVAB answer forms have been redesigned for processing via a Hewlett-Packard mark-sense reader from IBM card size…

Validities of the four aptitude indexes of the Armed Services Vocational Aptitude Battery (ASVAB), Form 1, and the Airman Qualifying Examination-66 (AQE), were determined for final grades in 46 airman training courses. Comparisons were made between AQE and ASVAB in terms of their ability to predict technical school success. The data demonstrate…

The purpose of this paper was to examine the factor structure of the Armed Services Vocational Aptitude Battery, Forms 8, 9, and 10. The analyses provided evidence of the replicability of ability constructs across diverse samples. (Author/PN)

Equating a new standard test to an old reference test is considered when samples for equating are not randomly selected from the target population of test takers, identifying two problems from equating from biased samples. An empirical example with data from the Armed Services Vocational Aptitude Battery illustrates the approach. (SLD)

Validity differences for a "g" (general factor of intelligence) score calculated on the Armed Services Vocational Aptitude Battery (ASVAB) alone versus the ASVAB plus 9 experimental tests were determined for 3,922 military recruits. A validity gain of potential utility was observed for hands-on performance measures. (SLD)

The validity of the subtests and composites of the Armed Services Vocational Aptitude Battery (ASVAB) for grades in 150 military technical schools was investigated with 88,724 Air Force recruits. Across all jobs, arithmetic reasoning was the most valid subtest, and the electronics composite was the most valid composite. (SLD)

Several confirmatory factor analyses were conducted on the Armed Services Vocational Aptitude Battery (ASVAB) with a nationally representative sample of 11,078 subjects. Based on fit indexes, simple structure, and parsimony in parameter estimation, a three-factor hierarchical model was chosen. Two factors resemble those of P. E. Vernon (1969).…

A study was conducted to investigate the reading comprehension and educationally related characteristics and relationships that describe the Navy's recruit population. The variable of primary interest was the recruit's reading comprehension grade level score; other variables were years of education, aptitude score, high school graduation status,…
