Data: An Essential Tool

“Sadly, too many people view (California's) diversity as a big problem. I don't. Instead, I say: Imagine! Imagine the potential of that diversity in today's—and tomorrow's—global economy. If we educate these students well, our state would not only be able to compete more effectively, but it would be able to lead our nation and the world economically. ”

—Jack O'Connell, California Superintendent of Public Instruction


Data is an essential tool for schools and their partners as they work to close the achievement gap. Data can expose deficits in school and community capacity and gaps in student achievement. At the same time, data can identify community assets and capacities that can be used to address challenges.

Effective use of data enables school communities to learn more about their school, pinpoint successes and challenges, identify areas of improvement, and help evaluate the effectiveness of programs and practices. School–community partnerships should look at data from both sides of the partnership from the outset. For example, both school data (such as grades, test scores, and attendance) and community data (such as information about the number and location of children unsupervised after school) should be used in the partnership-planning process. Assessments indicate some of the strengths and challenges of the school's instructional program and of individual students. Comparative data across schools and districts help to identify promising practices.

Knowing how to analyze, interpret, and use data enables informed decisions to be made in all areas of education, ranging from professional development to student learning. As part of an ongoing cycle of collaborative reflection, schools and their partners study the feedback offered by data to measure results and improve effectiveness. Data helps partners decide when to stay the course and when to make changes.

Data builds a knowledge base for future action, and it builds momentum for change. Data can provide evidence of improvement in academic outcomes linked to partnership activities. As schools and their partners strive to close the achievement gap, data enables them to make better choices and uncover better ways of serving students and the community.
