Procedures for correcting for guessing and for assessing partial knowledge (correction-for-guessing, three-decision scoring, elimination/inclusion scoring, and confidence or probabilistic scoring) are discussed. Mean scores and internal consistency reliability estimates were compared across three administration and scoring procedures for…

The Answer-Until-Correct (AUC) procedure has been proposed in order to increase the reliability of multiple-choice items. A model for examinees' behavior when they must respond to each item until they answer it correctly is presented. An expression for the reliability of AUC items, as a function of the characteristics of the item and the scoring…
