Abstract
Competency examinations in a variety of domains require setting a minimum standard of performance. This study examines the issue of whether judges using the two most popular methods for setting cut scores (Angoff and Nedelsky methods) use different sources of information when making their judgments. Thirty‐one judges were assigned randomly to the two methods to set cut scores for a high school graduation test in reading comprehension. These ratings were then related to characteristics of the items as well as to empirically obtained p values. Results indicate that judges using the Angoff method use a wider variety of information and yield estimates closer to the actual p values. The characteristics of items used in the study were effective predictors of judges’ ratings, but were far less effective in predicting p values
