National Cross-Validation of the Computerized Adaptive Screening Test (CAST)
Abstract
The Computerized Adaptive Screening Test (CAST) is used by Army recruiters to predict prospective applicants' subsequent performance on the Armed Forces Qualification Test (AFQT). A modified version of the CAST software was used in 60 recruiting stations across the country from January through December 1985 to collect CAST item-level performance information. Screening test data were matched to applicant records from Military Entrance Processing Stations to obtain ASVAB scores and relevant demographic information. The cross- validated, corrected correlation between CAST and AFQT scores is .83. CAST's ability to predict important AFQT performance categories and Army Aptitude Area scores was also examined. Alternative subtest lengths were evaluated and item bank characteristics were described. Keywords: Recruiting, Computerized adaptive testing (CAT), Enlistment screening test (EST).
