The advent of new technologies and increased access to robust connectivity is reshaping the K-12 landscape for teaching and learning. School districts nationwide are leveraging digital instructional materials and resources to deliver transformative and impactful personalized learning opportunities for students and to enhance the administrative coordination of school business. Educators are striving to meet the needs of the modern workforce including the need to develop life-long learners that can adapt to ever changing jobs and careers as technology continues to disrupt the digital age workplace. This report advocates for equitable, reliable, robust broadband access both on and off campus to prepare all students for life and work. This report builds upon SETDA's earlier work, including its groundbreaking Broadband Imperative series of reports and State Broadband K12 Leadership reports. Exemplars highlight states and districts where robust bandwidth has already positively impacted teaching and learning. [For the summary, see ED604818.
