Postdictions of College GPAs from ACT Composite Scores and High School GPAs: Comparisons by Race and Gender.
Crawford, Paul L.; And Others
"Postdictions" of college grade point averages (GPAs) from high school GPAs and/or American College Testing Program (ACT) composite scores were compared by gender and race for 1,121 freshmen and sophomore students at a West Virginia College. The sample included 945 white and 176 black students, and 553 males and 568 females. Significant differences in postdictions were found for race and gender with substantially greater frequencies of over/under postdictions when the ACT composite score was the only predictor variable. Significant differences between validity coefficients of two linear regression models were found. One model used combined ACT composite scores and high school GPA to predict college GPA, while the other made a direct prediction of college GPA from ACT composite scores. Results of the former model indicated that high school GPA contributed significantly to prediction efficiency. No significant gender or race differences were found between regression coefficients or intercepts in either predictive model. There were significant gender and race differences between high school GPAs, college GPAs, and ACT composite scores in all state universities and colleges. College GPAs were under-postdicted for female white students and over-postdicted for male students. Significant gender and race postdiction differences were found in different predictor models and from different sample pools. A 19-item list of references and 6 data tables are included. (TJH)
