The chapter uses lessons learned from the design, development, implementation, and improvement of a collective action network to focus on theory and practice at the nexus of educational leadership and social justice. A brief introduction honors those who came before in this work and operationalizes a challenge to reimagine the discourse and the practice of educational leadership for social justice. The challenge is then addressed in two sections. The first section "A Collective Action Network and Its Working Space," addresses how and why a collective action network was formed to pursue social justice in education. In this section, the conceptual frameworks that underlie the cross-sector partnerships constituting the network are explicated. Additionally, the nature of the work space created by the diverse experiences and expertise of partners is examined, including how three theoretical framespublic scholarship, improvement inquiry, and restorative justiceinform educational leadership for social justice. In the second section "Nodes in the Network: Grassroots Efforts in Pursuit of Social Justice," examples of projects that have been undertaken across seven nodes in the network are provided as illustrations of the diversity of discourses and practices that can contribute to the synergy that exists at the nexus of educational leadership and social justice. Each node in the network represents not only discrete cross-sector partnerships, but also discrete efforts to improve systems of practice, address harm, and authentic practices of social justice. The grassroots work includes improvement efforts that range from school improvement to principal preparation to violence prevention to police training to prison education to Community Learning Exchanges to elementary math instruction to holistic African American male achievement. A brief concluding statement indicates why the reimagining the discourse and the practice of educational leadership for social justice is a challenge worth pursuing.
