How should school leaders analyze data to inform the school vision according to best practices?

The correct approach for school leaders to analyze data in order to inform the school vision is to look at the data across grade levels and assessments. This method allows leaders to gain a comprehensive view of student performance and to identify trends and patterns that may not be visible when focusing solely on a single assessment type or specific cohorts. By examining data across various grade levels and multiple assessments, leaders can understand the effectiveness of instruction, address gaps in learning, and make informed decisions that support the overall vision of the school. This holistic analysis enables the development of strategies that can be applied school-wide, ensuring that improvements benefit all students, rather than just a specific group or subject area. By prioritizing broad data analysis, school leaders can foster a more collaborative and inclusive approach to achieving educational goals.
