Quo Vadis Racial Disparities? Trend Analysis of the Participation and Top Achievement in Advanced Placement Computer Science Exams

Abstract

This study explores the direction and magnitude of racial disparities on three advanced placement (AP) computer science (CS) exams, namely AP CS Principles, AP CS A, and AP CS AB, based on the test scores of more than one million students who have taken AP CS exams between 1997 and 2020. Using Mann–Kendall test and Sen's slope procedures we found that the number of Black, Hispanic, and Native American students in AP CS exams have increased steadily and significantly over years, yet they are still far from reaching parity. Further, our findings suggest that the racial disparities among top achievers are very wide. The results provide educators and researchers support for identifying and quantifying the racial disparities in advanced academic programs and may inform the development of policies, practices, and programs to reduce racial disparities in pre-college CS education and further.
