The document describes four models of school supervision: 1. The Classical Supervision Model features a hierarchical structure with central, regional, and district levels providing control over schools. It is comprehensive but costly and bureaucratic. 2. The Central Control Model stresses inspections of each school every few years by a centralized inspection body. It has clear roles but provides little support and too much stress on schools. 3. The Close-to-School Support Model focuses support on needy schools through district officers while regional and central levels have lighter control roles. It is flexible but may not cover all schools. 4. The School-Site Supervision Model eliminates external inspection and places full responsibility on school boards and staff
