THE ECAT BATTERY

The Enhanced Computer-Administered Test (ECAT) battery was selected by a Joint-Services panel of testing experts tasked with finding compute rized tests that were likely to increase validity when added to the Ar med Services Vocational Aptitude Battery (ASVAB). The tests are descri bed in this article and illustrated with sample items. Factor analysis of the ASVAB and ECAT battery showed that, although there is consider able overlap between the batteries, the ECAT battery measures 3 abilit y factors beyond those measured by the ASVAB: Working Memory, Spatial Ability, and Psychomotor Ability.
