As a leader in education, you have access to various sources of data and evidence that can inform your leadership decisions and actions. Student data, such as achievement, attendance, behavior, engagement, feedback, and well-being, can be used to monitor and improve student outcomes, identify and address gaps and disparities, and tailor support and interventions. Teacher data, such as performance, satisfaction, feedback, and development, can be used to evaluate and enhance teacher quality, provide recognition and reward, and foster professional growth and collaboration. School data, such as climate, culture, resources, processes, and results, can be used to assess and improve school effectiveness, efficiency, and equity, and to align practices and policies with your vision and mission. External data, such as research, benchmarks, standards, and best practices, can be used to compare and contrast your performance and practices with others, and to learn from and adopt proven and innovative strategies and solutions.
