RT Journal Article SR Electronic T1 The Value of a Higher ACT Exam Score JF Journal of Human Resources JO J Hum Resour FD University of Wisconsin Press SP 0922-12537R2 DO 10.3368/jhr.0922-12537R2 A1 Haggag, Kareem A1 Leslie, Emily A1 Pope, Devin A1 Pope, Nolan YR 2024 UL http://jhr.uwpress.org/content/early/2024/11/04/jhr.0922-12537R2.abstract AB Entrance exams are an integral aspect of the college admissions process. We use rounding in ACT composite exam scores to identify the causal effect of receiving a higher score. Using data for over 3 million test takers, we estimate that “randomly” receiving one extra point on the ACT leads to a 0.44 percentage point increase in the probability of attending a 4-year college. Our results have implications for the importance of entrance exams in the admissions process, the value of test preparation and retaking, and the inequities that can be created by unequal access to test prep and resources.
