This book puts into perspective and practices the vision of what supervision should be. It is a model of principal-teacher interaction and redefines the professional relationships of classroom supervisory practice. The Downey approach attempts to change how principals approach supervision by replacing it with a collegial, egalitarian model of professional practice. This approach is a model of changed supervisory practice that attempts to characterize an entire school to develop a network of relationships. The Downey approach is about changing schools one teacher at a time in order to attain a culture of high work-performance for the entire school.
