Over the past decade, schools, districts, and states have become increasingly savvy with data collection and analysis to drive student outcomes. The development and use of Early Warning Indicator and Intervention Systems (EWS) are at the cutting edge of the data- driven, outcomes-focused, high-impact education movement. These systems can increase educators' effectiveness by helping them use data to identify those students who are on track to graduate, and those who are falling behind, far enough in advance to provide appropriate interventions. This report represents the first national assessment of EWS at the district, state, and national levels. It shares evidence from the latest research and best practices from the field so that parents, educators, administrators, business leaders, and legislators can be better equipped to keep children on track to graduate high school, prepared for college and career success. Appended are: (1) The Civic Marshall to Build a Grad Nation; and (2) Additional Resources on Data Usage and Early Warning Indicator and Intervention Systems. A bibliography is included.
