The Army must meet quantity and quality goals in its recruiting. Recent advances in computer technology and psychometric theory have made possible a new type of assessment technique, called computerized adaptive testing CAT, that can provide accurate estimates of ability based on relatively few test items. The Computerized Adaptive Screening Test CAST was designed to estimate a prospects Armed Forces Qualification Test AFQT score at the recruiting station. Recruiters use prospects CAST scores to determine whether applicants should be sent to Military Entrance Processing Stations for further testing. These scores also forecast the various options and benefits for which the prospects will subsequently qualify. This report summarizes analyses from a nation-wide cross-validation study and recommends that changes be made to CAST to improve its utility to recruiters.
