Abstract
This report represents the results of an evaluation of English and Spanish language written knowledge tests that were administered to applicants for an original or renewal Class C driver license. The report presents test fail rates for multiple attempts, mean error scores, and internal consistency validity for each test form, as well as the pass rate, item-choice selection rates, and item-total correlation for each item on each English test form. Items that need to be reviewed for possible rewording or replacement are identified. The results are based on 11,307 completed test forms collected from all California Department of Motor Vehicle field offices on August 4, 2005, or for a few offices on a subsequent Thursday.
