Women of Color faculty remain underrepresented across all fields of postsecondary science, technology, engineering, mathematics, and medicine (STEMM). Although extant literature describes the collective institutional-level experiences of Women of Color faculty, an effort to understand the departmental-level experiences and contextually how the STEMM environment shapes these experiences is lacking. This mixed methods study draws from quantitative and qualitive data collected by a Faculty Worklife survey to interrogate how Women of Color STEMM faculty experiences within their department shape their retention. In defining which and exploring how elements of a STEMM departmental climate impact retention, quantitative analyses reveal that while a sense of belonging and inclusion positively predicts faculty retention, simply holding intersectional racial and gendered identities as a Woman of Color in STEMM negatively predicted faculty retention. Qualitative narratives supplement and expand statistical findings, shedding light on how the double-bind influenced incidents of hostile, intimidating, and exclusionary behaviors negatively impacted Women of Color faculty job satisfaction and retention. In understanding what factors contribute to, rather than subtract from retention, Women of Color faculty cite department chair advocacy and ongoing colleague research collaborations as primary reasons to stay. Together, integrated quantitative and qualitative findings shed light on the nuanced departmental aspects that shape Women of Color retention. Moreover, by applying the Theory of Racialized Organizations and Quantitative Critical Race Theory as guiding frameworks, this study took an intentionally critical and intersectional approach that humanized statistical data and uncovered how STEMM fields may function as racialized organizations that influence Women of Color faculty retention.
