This book outlines a process for showing how well a school or district meets its goal of sustained student learning. The first section provides a knowledge base for collecting and reporting educational data. The next section reflects the components of educational change and answers "how to" questions about data gathering, analysis, and reporting at the school level. The last four chapters show how it all fits together at the district level. These chapters describe the approach: (1) "Using Data To Align School Improvement"; (2) "Why Bother To Get Engaged with Data?"; (3) "The Status of Data Use (or Nonuse)"; (4) "Arousing the Passion"; (5) "So What's Significant?"; (6) "It Matters How It Looks"; (7) "Figuring Out What It Means"; (8) "People, Passion, and Proof in Goal Setting"; (9) "Digging Deeper"; (10) "Planning Your Work and Working Your Plan"; (11) "A Design for Data Day"; (12) "Communicating about Data"; (13) "Using Student Performance Data To Integrate District Curriculum Work with the School Improvement Process"; and (14) "Staying Off the Bandwagons." (Contains 33 figures.) (SLD)
