The American Talent Initiative's Student Success Research Grant Program supported research studies aimed at deepening our understanding of the institutional practices and strategies that can improve student success at high-graduation-rate institutions. The findings will offer actionable recommendations for supporting lower-income students, while raising awareness of the challenges that they--and the institutions that serve them--continue to face. Full manuscripts will be published this summer in the "Peabody Journal of Education." These short briefs aim to equip institutional leaders with key research insights, empowering them to implement strategies that foster meaningful, lasting change.
