While the legal precedent of affirmative action in U.S. higher education is well documented, graduate admissions practices that withstand strict scrutiny need further documentation. This chapter fills that gap in three ways. First, we briefly highlight the history of affirmative action in U.S. higher education as it relates to broadening the participation of URMs. Second, we offer best practices in U.S. graduate admissions that take into account the benefits of diversity while working within legal guidelines. We then close with considerations for future scholarship, policies, and practices.
