Many district and school leaders have leveraged instructional leadership or social justice leadership to advance student achievement for minoritized students. While research has examined these approaches separately, we identify a potential gap at the nexus between instructional and social justice leadership. In particular, we need further research examining how leaders bridge instructional and social justice leadership practices to disrupt educational inequities. Our study examines how educational leaders weave instructional and social justice leadership skills to cultivate others' social justice pedagogical knowledge and skill. Employing a collective case study framework, this study explores how a mid-sized urban district's superintendent and school leaders cultivated and promoted the social justice pedagogical knowledge and skill of others. Data was collected through interviews, surveys, and document reviews. The primary research participants included one superintendent, two assistant superintendents, three central office leaders, five school leaders, and six teachers. Our findings highlight four themes: the importance of leaders' critical self-reflection perceptions of district-level infrastructure and strategic planning, school-level instructional infrastructure and capacity building, and gaps in social justice pedagogical skill. This research has implications for practice, policy, and existing literature related to cultivating and enacting social justice pedagogical knowledge and skill across diverse contexts.
