Abstract
This study used the hindsight bias literature to examine the effects of providing test item answers on the level and predictive accuracy of Angoff cutoff score judgments. Subjects, randomly assigned to either an answers or a no-answers group, made Angoff judgments on items testing knowledge of driving law and vehicle operation. Items were catagorized into subtests based on empirical difficulty. Results indicated that providing answers interacted with subtest difficulty to influence the level of Angoff judgments. On the easiest subtest, those in the answer group made higher judgments than did those in the no-answers groups; the reverse effect was observed on the most difficult subtest.
