H. Wainer and L. Steinberg (1992) showed that within broad categories of first-year college mathematics courses (e.g., calculus), men had substantially higher average scores on the mathematics section of the Scholastic Aptitude Test (SAT-M) than women who earned the same letter grade. However, Wainer and Steinberg's analysis may lead to unwarranted conclusions in that they: (1) focused primarily on differences in SAT-M scores given course grades when the more important question for admissions officers is the difference in course grades given scores on the predictor; (2) failed to account for differences among calculus courses; and (3) focused on the use of the SAT-M as an isolated indicator. Reanalysis, taking distinctions among courses into consideration, suggests that Wainer and Steinberg's estimates were too large by about 10 points in calculus courses, although estimates for precalculus courses are confirmed. The reanalysis, which concentrated on 43 colleges, indicated that a more appropriate composite indicator made up of both SAT-M and high school grade point average demonstrated minuscule gender differences for both calculus and precalculus courses.
