The purpose of this qualitative descriptive study was to understand better the experiences of Black women, their unique encounters caused by the intersectionality of their race and gender, and the support strategies they rely on to navigate the environment of the United States STEM field. The study's theoretical foundations were the Critical Race Theory (CRT) and Intersectionality Theory. The lack of research concerning Black women's experiences in the STEM domain precipitated its exploration to expand the literature. The study included three research questions. First, how do Black women describe their experiences in the STEM domain? Second, how do Black women describe their unique encounters caused by the intersectionality of their race and gender in the STEM domain? Thirdly, how do Black women describe the support systems they use to navigate the androcentric STEM domain? Purposive and limited snowball sampling was used to select 16 Black women to participate in the study because of Black women's scarcity in STEM. Data were gathered through a 4-question open-ended questionnaire and an individual remote semi-structured open-ended interview. An inductive thematic analysis was used to analyze the study's data. These three primary themes emerged from the data: (1) STEM Curiosity and Interests, (2) Adverse Environment, and (3) Deliberative Practices. The deliberative practice's theme with 230 codes is the most prominent. The study's findings demonstrated how race and gender create oppressive factors for Black women in the STEM domain. Through these descriptive results, the researcher expanded the knowledge regarding Black women's unique experiences in the STEM domain.
