How do educators learn to be teacher leaders? In this qualitative survey research study, we explored perceptions of 227 former induction program participants concerning teacher leadership (65% response rate). Methodologically, we conducted qualitative coding of open-ended survey data. Defined teacher leadership, participants often referred to their mentor. They reported currently serving in a wide variety of teacher leadership roles. They suggested the induction program and their mentors nurtured them to become teacher leaders. Examining the data, we conclude that during the program mentors demonstrate to novices teacher leader characteristics, as they share best practices, model professionalism, and offer support. They normalize that leadership is simply a part of good teaching. When the participants graduate and work in classrooms, many draw upon their induction experiences and emerge as teacher leaders. Data suggest that to increase teacher leadership, more comprehensive, full-time mentoring induction programs are warranted.
