Purpose: Literature on teacher leadership highlights a significant gap in understanding the role of teacher leaders (TLs) as entrepreneurs. This research aims to bridge this gap by examining the multifaceted entrepreneurial dimension of teacher leadership. It specifically focuses on providing a comprehensive profile of these leaders and assessing their perceived influence on teachers' outcome, which are important for improving school performance. Design/methodology/approach: A two-step clustering procedure was utilized to discern profiles of teacher leaders' entrepreneurial behaviours, sampling 586 participants in a teacher leader training program. To assess mean differences in relation to perceived influence on teacher outcomes (i.e. job satisfaction, intrateam trust and innovative teaching practices) among these clusters, two-way contingency table analysis and MANOVA were conducted. Findings: We identified three teacher-leader profiles: congenial facilitators, champion-leaders and executors. Our findings reveal the unique strengths and weaknesses of each profile and their contributions to job satisfaction, intrateam trust and innovative teaching practices. Originality/value: This study is innovative in its detailed examination of teacher leadership through the lens of Teacher Entrepreneurial Behaviour (TEB), providing new perspectives on the intricate relationships between teacher leaders' TEB and their perceived influences. This deeper insight emphasizes the important role of entrepreneurial behaviours within teacher leadership, suggesting new directions for further research and development in educational leadership practices.
