This study of teacher leadership in first-year teachers included the following data sources: survey, follow-up telephone interviews, and teacher leader essays. Fifteen novice teachers responded to the survey, while three participated in follow-up interviews. Results suggest ideas of teacher leadership change from pre-service years to the end of the first year of teaching. Themes are shared from survey and interview findings. Follow-up interviews provide deeper understanding of those changing ideas of teacher leadership. Findings present how teacher leadership is connected to existing teacher development literature. Implications are made for teacher educators in states requiring teacher leadership for licensure.
