Abstract The authors analyzed self-reported SAT scores and actual SAT scores for five
different samples of college students (N=650). Students overestimated their actual SAT
scores by an average of 25 points (SD=81, d=0.31), with 10% under-reporting, 51%
reporting accurately, and 39% over-reporting, indicating a systematic bias towards over-
reporting. The amount of over-reporting was greater for lower-scoring than higher-scoring
students, was greater for upper division than lower division students, and was equivalent for
men and women. There was a strong correlation between self-reported and actual SAT
scores (r=0.82), indicating high validity of students' memories of their scores. Results
replicate previous findings (Kuncel, Credé, & Thomas, 2005) and are consistent with a
motivated distortion hypothesis. Caution is suggested in using self-reported SAT scores in
psychological research.
