Considerable work is still required to eliminate disparities in postsecondary STEM persistence and success across student groups. Engagement in faculty-mentored research has been employed as one strategy to promote personal, professional, and academic gains for undergraduate students, although barriers exist that make it more difficult for some to participate than others. In this article, we highlight three guiding strategies for structuring institutional diversity action plans that will help ensure equitable access to undergraduate research experiences. Relevant to these three strategies, we propose five specific tactics that educators and institutional leaders will find attainable in relatively short time frames, in addition to a questionnaire for institutional self-assessment related to these tactics. By following the recommendations outlined in this article, and thereby establishing an infrastructure for equitable access to undergraduate research experiences, we assert that institutions can begin to close educational achievement gaps, meet growing U.S. workforce demands, and uphold the democratic ideals of higher education.
