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…

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.

Proposes a procedure for empirical initialization of the trait (theta) estimator in adaptive testing that is based on the statistical relation between theta and background variables known prior to test administration. Illustrates the procedure for an adaptive version of a test from the Dutch General Aptitude Battery. (SLD)

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)

The scope and nature of sex differences in the Graduate Record Examination are explored by identifying individual test items that differ from the other items in terms of the magnitude of the difference in item difficulty for the sexes. In general, limited evidence of differences was established. (Author/CTM)
