This qualitative, interpretive study explored the perspectives of suburban public K-5 principals on their leadership of diversity, equity, and inclusion (DEI) work. Semi-structured interviews included 13 participants who have been serving as principals of schools with at least 300 students for over two years. The study's research questions focused on how principals define "the work" of DEI, the experiences of principals leading the work, and the levels of self-efficacy principals feel about their leadership of the work. The conceptual framework for this study considered Cobb and Krownapple's dignity framework for educational equity as principals work to shape a culture of equity to honor the dignity of all students. As participants defined the work of DEI, themes such as the significance of belonging, representation, courageous conversations around issues of social justice, appreciation and acceptance, and inclusion emerged. Principals described their experiences leading DEI work and shared how they navigated situations of social justice, the factors that influence their leadership of this work, the perceived barriers they experience, professional development they receive and lead, and their engagement with the community on this work. The self-efficacy principals feel about their leadership of this work was also explored. Four propositions based on the findings were shared: principals have high levels of self-efficacy on creating a welcoming environment and building a strong sense of belonging for all students; principals need additional training and resources to be more effective in their leadership of DEI work; principals in districts with a designated director of DEI feel more supported and are able to do more with equity and inclusion than principals without a DEI director in place; principals want support and clear expectations from the superintendent and district leaders on their leadership of this work. Implications for theory and practice, limitations of the study, and recommendations for future research are also included.
