In spite of the widening racial achievement gap among U.S. college students (U.S. Census Bureau, 2011), some universities are achieving success in supporting the graduation and postcollege goals of Black undergraduates (Apprey, Bassett, Preston-Grimes, Lewis, & Wood 2014/this issue; Baker, 2006; Hrabowski, 2003; Hrabowski & Maton, 2009). Although research has documented efforts to improve students' college academic success in mathematics, science, and engineering (Maton & Hrabowski, 2004), little research has examined the role of undergraduate support programs across the academic disciplines to bridge success for students from high school graduation through graduate school matriculation. This is a key link in the pipeline to career and lifelong achievement for Black students. The following case study describes an inclusive cluster-mentoring model for Black undergraduates at a Research I university that includes four elements--(a) student peer-advising, (b) faculty-student academic mentoring and advising, (c) culturally sensitive initiatives, and (d) organized parental support-to create high impact with measurable results. This university-based model can serve as a guide to improve and expand services that support the academic and leadership success of Black undergraduate students in other higher education settings.
