This study used empirical and simulated data to compare and contrast traditional measures of inter-rater reliability to a novel measure of inter-rater scoring differences in constructed response items. The purpose of this research was to investigate an alternative measure of inter-rater differences, based in modern test theory, that does not require a fully crossed design for its calculation. The proposed, novel measure of inter-rater differences utilizes methods that are …
