A new way to think together, work together, and impact students… together.

Despite regular meetings and planning sessions, collective leader efficacy often remains an untapped resource, leaving leadership teams working in silos and increasing the challenge of creating environments where every student and adult can thrive. Lead Collectively bridges this gap by providing a comprehensive framework for shared understanding, joint work, and evidence-based decision-making to strengthen leadership teams and amplify their impact on teaching and learning.

Drawing on decades of leadership experience and research, authors Peter M. DeWitt and Michael Nelson offer actionable tools, protocols, and insights to help educational leaders foster trust, coherence, and accountability. Additional features include: 

  • A step-by-step Collaborative Inquiry Cycle to guide leadership teams from identifying problems of practice to tracking measurable results
  • Guidance on integrating AI tools to analyze data, assess impact, and enhance collaboration
  • Case studies and real-world stories illustrating how schools and districts have transformed their leadership practices through collective efficacy
More than a guide, Lead Collectively is an invitation for leaders to foster collaboration to achieve meaningful, lasting change. Whether you’re leading at the school or district level, this book equips you with the tools to grow as a leader and drive measurable improvement for your students and educators.

about meaningful change in our schools.
