School culture encompasses the norms, values, beliefs, relationships, and shared behaviors that shape how a school operates. A positive school culture promotes high expectations, caring relationships, and shared responsibility for student success. To develop a positive culture, schools must assess their current culture, identify areas for improvement, and implement interventions like staff training, clear behavioral policies, and programs to support safety, learning, and relationships. Measuring multiple dimensions of school culture over time allows schools to strengthen this foundation for learning and growth.
