| Abstract: | This study attempted to determine whether individual differences in intra-individual consistency are reliable over time and whether future grades can be predicted more accurately for consistent students—those whose grades do not vary much from course to course—than for students with “spotty” records. Measures of intra-individual consistency were computed from grades obtained early in school and from grades obtained later for several samples of students. These measures showed no reliability over time, and there were no differences between consistent and inconsistent students with regard to the accuracy of prediction of future grades. It was recommended that considerable caution be used in attributing any significance to the degree of consistency or inconsistency manifested by a student's academic record. |
