Time management is crucial for school managers to allocate the appropriate time for academic, co-curricular, and sports activities. An annual plan should devote 70% of time to curriculum, 15% to co-curricular activities, and 15% to sports. The school day is divided into periods through a timetable. Each period's content and duration must be justified. Microplanning further divides periods into starting, main text, key points, and ending components. Homework load and exams are scheduled appropriately. The priority/payoff matrix model helps prioritize activities based on importance.
