We have been partnering with Educational Data Systems since 2000. We would not have been able to deliver our high quality MAC/MARS performance assessments and reports without them. They have been wonderful at communicating and supporting our member school districts and charter school networks. They continue to innovate and provide high quality data management tools to our work and our members.
