Although critical participatory action research (CPAR) has been cited as a means to cultivate more equitable systems in education, its promise has not been fully realized as a mechanism to enhance the experiences of minoritized cultural groups in U.S. higher education. As outsiders within academia who are multiplicatively marginalized, Black women's engagement in CPAR demonstrates unique potential to address this gap. In this paper, I introduce an agentic diversity, equity, inclusion, and belonging strategy embedded in a critical action research methodology known as a participatory action research counterspace (PARC). After situating the proposed methodology in existing literature, I describe a PARC study involving a group of Black women students, faculty, staff, and administrators at a predominantly white institution (PWI), as well as the defining contours of the methodology. A discussion outlining the benefits of the PARC methodology for Black women enrolled and employed in higher education is also included.
