Mismatched Students, Missed Opportunities

Theoretical frameworks on mismatch, rooted in affirmative action literature, provide divergent conclusions on how overmatch, a synonym for affirmative action, and undermatch shape degree completion outcomes for Black undergraduates at selective postsecondary institutions. Through examining data from the 2003–2009 Beginning Postsecondary Students Longitudinal Survey, this study creates an academic index that estimates the precollege academic credentials of approximately 650 Black, first-time undergraduates enrolled at the top three tiers of selective colleges during the 2003–04 academic year to examine the effects of undermatching or attending a college that is less rigorous than a college that matches their precollege academic record. The findings suggest that overmatched Black students who enrolled at the most selective institutions were far more likely to graduate than students with similar precollege academic credentials who enrolled at their best academic match. The results also indicate that undermatching had an adverse effect on degree completion rates.
