Data Analysis for Continuous School Improvement, Third Edition, is a call to action. It is about inspiring schools and school districts to commit to continuous school improvement by providing a framework that will result in improving teaching for every teacher, and learning for every student, through the comprehensive use of data. It provides a new definition of improvement, away from a singular focus on compliance, toward a true commitment to excellence. This Third Edition is the culmination of over 25 years of doing the hard work in schools and districts, both nationally and internationally, to analyze, report, communicate, and use multiple measures of data for continuous school improvement. This book provides new and very specific tools, timelines, and strategies that will help schools and districts become true learning organizations.
