Empowering educators through teacher leadershipTeaching is critical and complex work, and expectations for students and schools are higher than ever. Without ongoing opportunities for learning and collaboration among teachers, meeting those expectations becomes even more difficult. According to the Alliance for Excellent Education (2005), "The single most important factor in determining student performance is the teacher." Implementation of a teacher leadership system paves the way for more support and greater collaboration for all teachers to learn from each other. As teachers' capacity for success increases, so does their ability to positively impact students.
