Notes that, by guessing, children may score within normal range on tests by chance alone. Describes one process, random guessing, for estimating "true blind guessing score" (range of scores) that, if known, would result in missing fewer at-risk children. Sensitizes test administrators to tests that do not address or have suspicious corrections for…

A modified beta binomial model is presented for use in analyzing random guessing multiple choice tests and taste tests. Detection probabilities for each item are distributed beta across the population subjects. Properties for the observable distribution of correct responses are derived. Two concepts of true score estimates are presented.…

The effectiveness of a model for determining a minimal cut-off score for criterion-referenced tests was examined. The model, based upon techniques presented originally by Nedelsky and by Angoff, was first used in conjunction with a multiple choice test developed for use in certifying school counselors in Georgia. A "knowledge estimation panel" was…
