The organization of a school can best be understood as a loosely coupled set of overlapping systems: the student system concerned with student education and development, the faculty system concerned with maintaining professional standards and effective teaching, the parent system focused on the relationship between the school and the child, and the administration system concerned with the management of the whole, including security and external relations. A good school climate can be seen as facilitating communication among these systems, which otherwise can easily degenerate into suspicion and mutual hostility.
