This study examined the impact of racial and gender intersectionality on science, technology, engineering, and mathematics (STEM) identity development and the academic achievement of Black female STEM undergraduates attending an HBCU. Research has demonstrated that the intersection of race and gender are likely to subject Black women to prejudice and ostracism in STEM disciplines. Data revealed that Black women experienced racial and gender intersectionality, but that quantitative findings demonstrated a decrease in Black racial centrality and private regard over time. Qualitative reports suggested otherwise. Further research must be done to understand the differences between the quantitative and qualitative findings.
