This document discusses different types of plans used in educational management, including single-use plans and school development plans. Single-use plans are created for non-recurring issues and include budgets and programs. They are meant to solve a specific problem and become obsolete once their purpose is achieved. In contrast, a school development plan is the school's strategic plan for continuous improvement over time, focusing on priorities like literacy, numeracy, and reducing the impact of poverty on student outcomes. The plan guides the school's actions and resource allocation through a cycle of self-evaluation, strategic planning, implementation, and reviewing impact.
