Creating thriving educational environments requires more than effective systems or strong leadership; it begins with people. This session explores two essential, research-based dimensions of whole-school wellness often overlooked in school improvement efforts: the well-being of school principals and the sense of belonging experienced by students. Drawing on two qualitative studies in North Carolina schools, the researchers examine how principals’ personal, psychological, and professional wellness, combined with students’ sense of belonging, shape school climate, engagement, and achievement. Principals and school leaders are uniquely positioned to champion this work through daily practice, school culture, and strategic vision. This session provides practical tools, reflective practices, and real-world insights to help leaders cultivate schools where wellbeing is foundational for themselves, their staff, and their students alike.
