From Fall 2019 through Spring 2020, The Hunt Institute released a series of policy briefs, "Attainment for All: Postsecondary Pathways," that highlighted scalable state-level strategies to boost postsecondary attainment rates among specific student subpopulations including high school graduates, first-generation students, and adult learners. Building upon the momentum of this series, the higher education team at The Hunt Institute has created a follow-up series of briefs that further explore the intersection between equity and efforts to raise postsecondary attainment rates. This is the last brief of the three-part "Attainment for All: Equity in Postsecondary Pathways" series. This brief brings the discussion on equity full circle by examining the use of disaggregated data to narrow equity gaps in postsecondary education. [For the first brief, see ED599441.
