This article examined root causes of the equity gaps in dual enrollment through a systematic literature review of peer-reviewed literature, public scholarship, and practitioner perspectives. Root causes identified include access barriers, lack of advising and support, lack of awareness, and financial barriers for underrepresented students, all of which contribute to lower participation rates for Black and Latinx students when compared with White and Asian students. This article serves to provide community college practitioners with a deep understanding of the factors that contribute to this problem so that they can identify interventions that will address these root causes. Suggestions for mitigating equity gaps in dual enrollment for underrepresented students through the use of targeted messaging campaigns are discussed.
