Teacher leaders can lead quietly in their classrooms through building knowledge, conducting research, reflecting on their practices, and aligning beliefs and actions. They can also lead more visibly by advocating for themselves, students, colleagues, and the teaching profession. This includes finding mentors, joining professional organizations, and sharing research. While advocating requires risks, clear goals and planning can help. The difference between an effective teacher and teacher leader is that leaders influence beyond their own classrooms, while professionals continue learning and contribute to the teaching field.
