Performance measurement in educational leadership is primarily used to hold schools and districts accountable for the academic achievement of their students. This information is used to make decisions about funding, resource allocation, and educational policies.

Financial data is not typically used as a performance measure in educational leadership. Instead, student achievement data, teacher evaluation data, and school climate data are more commonly used to assess the effectiveness of educational programs and policies.

Summative assessment is used to evaluate student learning at the end of a unit or course, while formative assessment is used to provide feedback to students during the learning process. Summative assessment is typically used to make decisions about grades and promotion, while formative assessment is used to help students identify areas where they need to improve.

An effective accountability system in educational leadership includes clear and measurable standards, a system for collecting and analyzing data, a process for providing feedback to schools and districts, and consequences for schools and districts that do not meet standards. These components work together to ensure that schools and districts are held accountable for the academic achievement of their students.

Performance measurement and accountability systems can be used to improve educational leadership by providing feedback to educators on their teaching practices, identifying areas for improvement in educational systems, making decisions about funding and resource allocation, and developing and implementing educational policies. These systems can help educational leaders to make informed decisions about how to improve the quality of education for their students.
