The Early Warning System (EWS) was originally developed by the National High School Center at AIR to calculate automatically the high-yield indicators related to dropout. In collaboration with the Center, the Texas Comprehensive Center (TXCC) adapted the EWS to produce a customized database version called the Early Warning Data System (EWDS).
EWDS collects data on research-based dropout indicators: academic performance, attendance, and behavior. Students who are identified as potential dropouts are flagged and provided with interventions that are also tracked in the database. To support implementation, the TXCC provided training around the state on using the EWDS free of charge to Texas schools and districts.
