This research investigates the connection between the leadership styles of school leaders, based on the Full Range Leadership Model (transformational, transactional, and laissez-faire), and their effect on the professional growth of public elementary school teachers in the Sariaya West District. Employing a descriptive-correlational methodology, the study analyzes how different leadership styles affect five essential elements of professional development: content focus, active learning, coherence, sustained duration, and collective participation, as outlined by Desimone and Garet (2001). The findings indicate that transformational leadership is the most common, fostering motivation, creativity, and tailored support for educators. Transactional leadership focuses on organized management and rewards, promoting responsibility and outcome-oriented behavior. Laissez-faire leadership shows moderate effectiveness by providing freedom while necessitating occasional support. The research reveals strong positive relationships between different leadership styles and aspects of professional development, with a well-rounded application of Full Range Leadership being the most effective. The results emphasize the need for flexible and cohesive leadership approaches to improve educators professional growth and involvement. The implications and suggestions highlight the significance of aligning professional development efforts with leadership methods to enhance educational results.
