In the wake of the accountability movement, school administrators are inundated with data about their students. How can they use this information to support student achievement? Data Wise presents a clear and carefully tested blueprint for school leaders. It shows how examining text scores and other classroom data can become a catalyst for important schoolwide conversations that will help schools capture teachers' knowledge, foster collaboration, identify obstacles to change, enhance school culture and climate, and improve students' results. The rich experience of the contributors--among them exemplary school leaders and top scholars in the field of statistics and testing--is reflected in the case studies that illustrate each chapter.
