title: The analysis of performance criteria defining course grades as a determinant of college student academic performance.
abstract: A series of five experimental conditions were designed to investigate the influence of minimum performance criteria and grade labels on college student academic performance. A college course in abnormal psychology was taught in an individualized manner so that each student could perform on each unit of subject matter in individual performance sessions whenever he wished. In each of the five experiments the minimum performance criteria that had to be attained before progressing to the next unit were varied during the quarter and the resulting changes in performance were recorded. In Experiment I there were no criteria; in Experiments II, III, and IV three levels of criteria (High, Medium, and Low) were varied but all of the criteria defined a course grade of "A". In Experiment V, the three criteria defined course grades of A, B, and C. The results showed that the criteria controlled performance to a high degree, so that regardless of what quality of performance had been demonstrated previously or was being produced currently, performance was immediately changed to attain new criteria put into effect. Students in Experiment I produced very poor performance compared to the other conditions.
