The Angoff and Nedelsky methods are two well-known procedures for setting passing scores on tests. Previous comparative studies indicate that the Nedelsky method tends to consistently set the lowest passing score relative to the Angoff and other methods. However, it cannot be concluded that the lower Nedelsky estimates are less accurate, because previous studies have not included a criterion of the "correct" passing score against which Nedelsky and other passing scores could be validated. The present paper describes an experiment in which criterion measures of the "correct" passing scores were generated and were compared for accuracy to Angoff and Nedelsky estimates.
