Abstract
College students (N = 198) predicted their grades at the beginning of four grading periods of a school year. Average discrepancy scores (ADS) between the self-predicted grade point average (SP GPA) and achieved grade point average (Ach GPA) were obtained for all students. Students in the top quartile (inaccurate predictors) were compared with students in the bottom quartile (accurate predictors) on five dimensions. No differences were found in sex or age. Accurate predictors tended to differ from inaccurate predictors in academic classification (p=.01), academic achievement (p=.001), and self-concept (p=.001).
