Do standardized test scores predict college grades better than high school GPA?
Core argument: Analyzing admissions and transcript records at multiple Ivy-Plus colleges, the authors find SAT/ACT scores predict first-year college grades with a normalized slope four times greater than high school GPA, conditional on race, gender, and socioeconomic status.
We analyze admissions and transcript records for students at multiple Ivy-Plus colleges to study the relationship between standardized (SAT/ACT) test scores, high school GPA, and first-year college grades. Standardized test scores predict academic outcomes with a normalized slope four times greater than that from high school GPA, all conditional on students’ race, gender, and socioeconomic status. Standardized test scores do not underpredict college performance for students from less advantaged backgrounds. Collectively these results suggest that standardized test scores provide important information to measure applicants’ academic preparation that is not available elsewhere in the application file. While some of the raw correlation between these variables relates to students’ demographic characteristics, much remains even when controlling for these variables. In contrast, high school GPA does not predict academic performance nearly as well. We also find no evidence of bias against students from less advantaged backgrounds, as students from such backgrounds do not outperform (and in some cases underperform) other students with the same test score
