This study investigated prediction of SJT item difficulties (ns = 35,139 – 42,561 for two tests) by SME ratings of SJT response effectiveness. About 30 subject matter experts rated forty SJT items. Findings indicated that SME ratings predicted difficulty, and certain characteristics (rater job level) affected these predictions.
