This study applied Bandura's (1986) social cognitive theory (SCT) and Gray et al.'s (2018) ecological framework to explore a sense of belonging among Black undergraduates pursuing a degree in business. This study sought to understand how Black students perceive a sense of belonging at the business school of City University (CU), a predominantly White institution (PWI), and to determine whether interpersonal, instructional, and institutional structures in the school environment influence belonging. Data analysis included open, axial, and selective coding using in vivo and a priori codes to identify emergent themes aligned to the conceptual framework. Findings indicate that Black students' perceptions of belonging are influenced by multiple factors within the business school environment. Prior community, cultural, and K-12 educational experiences shaped students' unconscious anticipation of belonging and beliefs about its importance. Key interpersonal factors affecting belonging included connection, academic engagement, unconscious bias, and microaggressions experienced primarily through peer and faculty interactions. Instructional and institutional factors in the curriculum had both positive and negative effects on participant's belonging. The study demonstrated triadic reciprocity as interpersonal and instructional structures influenced participants' belonging and cognitions, which in turn informed their behaviors, supporting both ecological and SCT frameworks. This research illuminates environmental factors within CU's business school that may influence Black students' sense of belonging and their pursuit of business education and careers. These findings may inform approaches to enhance programs, curricula, and institutional structures to improve perceptions of belonging among Black business students at CU.
