This chapter discusses mentoring strategies to facilitate the skill set development of teacher leaders through engagement, co-teaching, coaching, and reflection. It has two goals. The first is to facilitate the development of teacher leaders who are independent learners capable of creating new practice, deriving new concepts from new practice, and connecting those concepts to educational theory and research. The second is to develop in teacher leaders the capacity to mentor teacher candidates, early-career teachers, and future teacher leaders. As teacher leaders gain more practice with the new design, both their confidence and their expertise will grow until the process expands into a fully implemented new process within a larger, more complex system. Teacher leaders can generate new experiences and foster innovation through co-teaching. Coaching for teacher leaders focused on facilitating their ability to design and implement instructional innovations. Reflection for teacher leaders focused on the development of schemas associated with the innovation of new teaching strategies.
