Black women are the most influential racial group interested in education as a profession; yet. it is rare for them to attain senior-level roles within predominantly White institutions. The problem addressed by this study was that a significant number of Black women administrators in higher education throughout the United States are not advancing into senior-level positions within predominantly White institutions. The purpose of this qualitative case study was to explore why a significant number of Black women administrators in higher education are not advancing into senior-level roles within predominantly White institutions. In addition, this study was grounded using the critical race theory, with special attention given to issues of intersectionality to highlight Black women's experiences working in environments dominated by Whites. This study was also conducted using a qualitative comparative case study design to capture the attitudes and shared experiences of Black women working in different geographical locations. Ten Black women administrators who currently work or who have previously worked in a predominantly White institution in a low-to- mid-level position were interviewed by phone following a set of semi-structured interview questions. Content analysis of the interview responses was used to reveal how racial and gender identities affect Black women's experiences and their advancement opportunities into senior-level roles within predominantly White institutions. The findings of this study revealed that Black women administrators employed within predominantly White institutions believe their racial and gendered intersectionalities serve as aggravating factors that contribute to their inability to advance into senior-level positions. Additionally, data generated from this study cultivated several implications, suggesting that within predominantly White institutions, Black women are subjected to stigma and stereotypes, racial discrimination, lack of opportunities, and the lack of mentorships amongst individuals who share the same intersectional characteristics.
