Book excerpt: In an increasingly complex context of global pandemic, economic uncertainty, increased racial inequities, and a climate crisis, this practical guide for school leaders explores how capacity as learning at the individual, team, and organizational level can help schools become more agile and adaptive. Author James A. Bailey unpacks a new model of capacity building that combines learning process, leadership mindsets, and skills to enhance learning. This research-based book includes a "Diagnostic for School Learning Capacity" and "Team Considerations" to help school leaders and their teams launch further discussions and advance learning in their contexts. The tools in this timely book are designed to help school leaders handle the increasing volatile, uncertain, complex, and ambiguous world in which schools now exist.
