This document summarizes a case study examining the impact of elementary school principals' leadership behaviors on school culture and climate. The study analyzed principals' scores on the Leadership Profile assessment, which evaluates behaviors in building relationships, organization, decision-making, and goal achievement. It found that the principals' scores on structure and authority most influenced teachers' perceptions and the school culture. While principals were usually aware of their own preferred behaviors, they lacked awareness of how behaviors driven by underlying needs and stresses impacted faculty trust and relationships. This highlights the importance of principals understanding how their personal behaviors shape school culture and climate.
