Research indicates today's schools are different from those in the past. The traditional view of school leadership is not the mindset in today's educational institutions. Principals are no longer the sole decision makers regarding what takes place in the schools. With increasing levels of accountability, there is a greater need for collaboration and shared decision making. The purpose of this correlational study was to examine the relationship between teachers' perceptions of their principal's leadership behavior and the level of shared decision making practiced in their schools. This study sought to answer the following overarching research question: "To what degree is there a relationship between the leadership behaviors of secondary school principals and the level of shared decision making in selected Southeast Georgia schools as perceived by teachers?" Data were collected from secondary school teachers throughout Southeast Georgia using the Leadership Practices Inventory--Observer and the Shared Education Decisions Survey--Revised. Results indicated the highest leader practices identified to be encourage the heart and inspire a shared vision. The highest shared decision making dimension was pupil personnel services, followed closely by curriculum and instruction. Though very little relationship was found between leader behaviors and shared decision making as perceived by teachers, results from this study may be useful to principals who are considering shared decision making opportunities for their faculties.
