In this article, we revisit the radical roots of adult education for social change by developing community-based anti-racism education through participatory action research. Drawing on critical race theory (CRT) as its theoretical framework, we incorporate principles of participatory action research (PAR) to conceptualize community-based anti-racism education where community members and academics collaborate as equal partners throughout the process. Three key features emerged out of this analysis to characterize this approach: using people's lived experiences as an entry point to understand contemporary forms of racism, underscoring the importance of participation at the grassroots level, and prioritizing an action-oriented feature of community-based anti-racism education. By combining synergies between CRT and PAR, this approach has the potential to contribute to facilitating collaborative, equitable partnerships in practicing anti-racism education in diverse communities and enabling action-oriented anti-racism education as a site of advocacy, emancipation, and institutional practice for social change.
