Harnessing Formative Data for K-12 Leaders prepares school and district leaders to re-evaluate how real-time formative data can inform policy, planning, and professional development. The importance of effective formative data use has escalated since the expansion of distance learning and the integration of digital education tools, which have impacted the consistency, accuracy, availability, and actionability of data points that leaders rely on. This book's strategic insights into actionable, organizational-level formative data use will yield differentiated supports for schools to foster greater academic outcomes, a culture of equity and social-emotional well-being, and students' readiness for college, career, and lifelong learning. Each chapter includes connections to social justice, best practices for applying data points and field-tested tips for technology integration, and a host of interactive planning guides to support implementation.
