Building and Deploying an Early Warning System: Lessons Learned from a Large Scale Pilot
In the spring of 2013, Wisconsin piloted an Early Warning System (EWS) for middle school students
in 34 schools with more than 5,800 students. The EWS was built on free and open source tools
using Statewide Longitudinal Data System (SLDS) data. The process of moving from analysis to
pilot is discussed and the results of the pilot—including lessons learned for
scaling up the system statewide.
