Prediction of Grades in College Mathematics Courses as a Component of the Placement Validity of SAT-Mathematics Scores. College Board Report No. 89-9.
Bridgeman, Brent; Wendler, Cathy
If it can be shown that the Scholastic Aptitude Test mathematics test (SAT-M) is a reasonably good predictor of success in particular mathematics courses, it may have a role as a measure of prerequisite skills. The predictive validity of the SAT-M was studied by collecting grades from freshman mathematics courses at 10 colleges (3,499 students). Compared to tests that were specifically designed for placement purposes, the SAT-M score was a relatively poor predictor of grades in most courses. Even after correcting for the considerable range restriction that may occur when within-course scores are analyzed, coefficients were typically only in the mid 0.30s (compared to corrected coefficients for a local placement test that ranged from the high 0.40s to the low 0.60s). Nevertheless, the SAT-M significantly improved predictions from high school grade point average (GPA) alone, especially for calculus courses. In courses at all levels, grades of males and females were similar, but SAT-M scores of males were significantly above the scores of females. Gender differences could be reduced or eliminated by considering high school GPA with SAT-M scores. For algebra versus calculus placement decisions, a weighted composite of SAT-M and high school grades predicted 64% to 71% of actual placements. For precalculus versus calculus, about 80% of the actual placements could be predicted. Appendixes describe the colleges in the study, show grade predictability in three tables, and give sample items from the SAT-M. (Contains 6 figures, 21 tables, and 12 references.) (SLD)
