Successful supervision is broad-based and collegial, and positively affects both teaching and learning. Successful teaching is characterized by professional decision making facilitated by supportive supervision. The most powerful type of learning is student-driven, teacher-facilitated learning. Successful supervision, teaching, and learning are congruent and reflect one another, creating a "hall of mirrors." Supervision, teaching, and learning can both contribute to and flourish across 10 dimensions of successful schools, including care, service, trust, democratic community, equity grounded in equality, justice and peace, symbols and ceremonies, freedom and creativity, holistic development, and school vision. Reviews of literature on the dimensions of successful schools indicate a variety of positive benefits for schools, teachers, and students.
