Implications of Racial-Group Test Score Gap for College Admissions
September 29, 2020 (Tuesday)
Many college admissions committees are faced with a dilemma. On one hand, they would like to diversify their student bodies with respect to socioracial groups and racialized ethnic groups of Color. On the other hand, with respect to Black students in particular, there exists a long history of Black students obtaining lower scores on tests of cognitive abilities and skills relative to White students. The so-called test-score gap is obtained by subtracting the mean scores of Black students (usually the lower score) from the mean scores of White students (usually the higher score). The resulting differences or gaps are generally interpreted as evidence of the cognitive/intellectual impairment of the Black test takers, although various rationales have been offered for the disparities including environmental factors (e.g., social class differences) or racial-cultural bias in the test content. Consequently, universities historically have been legally challenged for admitting Black students with lower test scores than some White student(s) with a higher test score(s). Yet missing from analyses of the gaps is any focus on the effects of disparate sample sizes on the gaps’ magnitudes and on the standard deviations used to estimate the meaningfulness of the disparity between racial group’ test-score means.
In this presentation, I illustrate (a) the methodology for determining each racial group’s contribution to performance gaps on tests, such as the SAT and (b) the effects of disparate sample sizes on standard deviations. Stability in the magnitude of the gap overtime may be attributable to the relative stability of disparities in sample sizes. Admissions committees should consider (a) challenging the legal restrictions that prohibit use of separate racial group norms for selection purposes and/or (b) foster the development of assessment procedures that do not rely on parametric statistics.
