The purpose of this qualitative transcendental phenomenological study was to understand the meanings ascribed by multiracial male and female NCAA Division I student athletes in the Southeast region of the United States to the lived experiences of stereotype threat. Stereotype threat is a phenomenon that is boundless and can influence any individual who adopts an individual or group-based social identity (Steele, 2011). Stereotype threat, as a theoretical framework was developed as part of Steele and Aronson's (1995) research on the phenomenon of underperformance, which extends social identity theory. Specifically, underperformance is defined as a performance behavior that is uncharacteristic of someone who otherwise has demonstrated competency and mastery over the achievement domain for which the person performs (Steele, 2011; Steele & Aronson, 1995). By exploring the stereotype threat experiences of multiracial collegiate-athletes, this study extended the research of Comeaux (2012), Harrison (2012), and Steele (2011) who proved the existence of stereotype threat experiences among monoracial populations. For this study, analysis of respondents' verbalizations revealed 21 invariant constituents which were clustered into five themes. The modified Van Kaam method was used to create textual structural descriptions of the stereotype threat phenomenon. The interpreted results include six essences of stereotype threat. In addition to participant narratives, tables and figures help foster the reader's contextual understanding of the participants and their stereotype threat experiences. Contemporary scholars have opportunities to extend the research and to suggest ways to apply findings to the practical situations of multiracial student athlete populations.
