This report offers a first school-level look at how early warning systems are being implemented. The research team visited middle and high schools in cities across the country to observe how they are using EWIs to monitor and respond to student needs. The team explored five themes that describe how the EWI process is working in selected schools: 1) professional development and start-up for teachers and administrators, 2) identifying the Focus List of students for intervention (students who finished the previous school year with low attendance, poor behavior, and/or failed math or English), 3) the EWI meeting process, 4) EWI data systems, and 5) interventions and follow-up activities.
