Stephen D.H. Hsu (Dept. of Physics, Univ. of Oregon), James, Schombert (Dept. of Physics, Univ. of Oregon)

TL;DR
This study analyzes university records to explore how SAT scores relate to college GPA, revealing that high achievement is possible across a wide range of SAT scores and that combined SAT and high school GPA are strong predictors.
Contribution
It provides new insights into the correlation between SAT scores and GPA, highlighting the potential for students with lower SAT scores to succeed through effort and proposing a combined predictor for academic performance.
Findings
Correlation between SAT and GPA ranges from 0.35 to 0.5.
High GPA students often have below-average SAT scores.
Combined SAT and high school GPA predict college GPA effectively.
Abstract
We analyze a data set comprised of academic records of undergraduates at the University of Oregon from 2000-2004. We find correlations of roughly 0.35 to 0.5 between SAT scores and upper division, in-major GPA (henceforth, GPA). Interestingly, low SAT scores do not preclude high performance in most majors. That is, the distribution of SAT scores after conditioning on high GPA (e.g., 3.5 or even 4.0) typically extends below 1000 (the average among test takers). We hypothesize that "overachievers" overcome cognitive deficits through hard work, and discuss to what extent they can be identified from high school records. Only a few majors seem to exhibit a "cognitive threshold" -- such that high GPA (mastery of the subject matter) is very unlikely below a certain SAT threshold (i.e., no matter how dedicated or hard working the student). Our results suggest that almost any student admitted to…
