1. Instructional Subsystem: This focuses on the teaching and learning process itself. It includes curriculum development, lesson planning, classroom management, assessment, and teacher training.
2. Administrative Subsystem: This manages the operational aspects of the school. It encompasses budgeting, staffing, facilities management, student enrollment, and record-keeping.
3. Support Services Subsystem: This provides auxiliary services to support the instructional and administrative subsystems. Examples include transportation, food services, counseling, health services, and special education programs.
These are just three examples, and other valid subsystems could be defined depending on the level of detail and the specific school system.
