This research examined whether non-"g" residuals of the SAT and ACT subtests, obtained after removing g, predicted specific abilities. Non-"g" residuals of the verbal and math subtests of the SAT and ACT were correlated with academic (verbal and math) and non-academic abilities (speed and shop), both based on the Armed Services…

New items are being calibrated for the next generation of the computerized adaptive (CAT) version of the Armed Services Vocational Aptitude Battery (ASVAB) (Forms 5 and 6). The requirements that the items be "good" three-parameter logistic (3-PL) model items and typically "like" items in the previous CAT-ASVAB tests have…

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…

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).…

Twelve structural models of similarity were fitted to data from conventional and computer adaptive test (CAT) batteries measuring the same aptitude in a double cross-validation design. Three of the 12 models, including a multiplicative structure model, performed well, providing support for using CATs as replacements for conventional tests. (NSF)

When the network-flow algorithm (NFA) and the average growth approximation algorithm (AGAA) were used for automated test assembly with American College Test and Armed Services Vocational Aptitude Battery item banks, results indicate that reasonable error in item parameters is not harmful for test assembly using NFA or AGAA.

Outlines the development of a new interest inventory based on the RIASEC (Realistic, Investigative, Artistic, Social, Enterprising, Conventional) model. Rigorous development procedures and outcomes of a large validation study attest to the inventory's validity and reliability; it was found to be psychometrically sound and systematically correlated…

A method is presented and illustrated for simultaneously generating multiple tests with similar characteristics from the item bank by using binary programing techniques. The parallel tests are created to match an existing seed test item for item and to match user-supplied taxonomic specifications. (SLD)

Model-based equating was compared to empirical equating of an Armed Services Vocational Aptitude Battery (ASVAB) test form. The model-based equating was done using item pretest data to derive item response theory (IRT) item parameter estimates for those items that were retained in the final version of the test. The analysis of an ASVAB test form…

This book documents the research, development, and implementation efforts that allowed the U.S. Department of Defense to initiate the Computerized Adaptive Testing Armed Services Vocational Aptitude Battery Program for enlistment testing. Traces the history of this program over 30 years. (SLD)

Research on military reading abilities has shown a direct relationship between reading ability and training and job performance. The objectives of this study of the development of a reading scale were to: (1) measure the reading ability of military applicants using six commonly used reading tests; (2) use the Armed Services Vocational Aptitude…

The Armed Services Vocational Aptitude Battery (ASVAB), composed of the common elements of operational classification batteries used by the different services, has been given to high school students since 1968. Results are used by the schools for counseling and by the Armed Services for selecting and classifying potential recruits. The present…

In connection with the development of item pools for the Navy's experimental Computerized Adaptive Testing (CAT) system, items in five different content areas (General Science, Paragraph Composition, Word Knowledge, Math Knowledge, and Arithmetic Reasoning) have been calibrated using item response theory (IRT) methodology. Operational Armed…

The Navy Personnel Research and Development Center is developing a computerized adaptive test (CAT) administration, scoring, and reporting system for use in the selection and classification of military applicants. Scaling of the CAT version of the Armed Services Vocational Aptitude Battery (ASVAB) will produce CAT scores comparable to the current…

The Computerized Adaptive Testing (CAT) project is a joint Armed Services coordinated effort to develop and evaluate a system for automated, adaptive administration of the Armed Services Vocational Aptitude Battery (ASVAB). The CAT is a system for administering personnel tests that differs from conventional test administration in two major…
