The purpose of this study is to enhance our understanding of how a Historically Black College and University (HBCU) is cultivating Black male achievement in STEM. In this in-depth qualitative case study, we explore 2 resource-intensive and successful STEM pathway programs at Morehouse College, the only all-male HBCU in this country, as an opportunity to examine the cultivation of Black male STEM scholars. Our study was guided by 2 overarching questions: What opportunities for participation in a rigorous STEM education do the programs provide? What individual and institutional practices contribute to STEM student persistence and learning?
