The collective efficacy of teachers’ instructional practices has an outsized impact on raising student achievement. Yet, we struggle to leverage this strategy. Hattie indicates CTE has an effect size of 1.57, when the annual growth size is 0.4. Teachers need to harness the power in their planning. De Pere and Racine school districts, as well as NextPath Education, will demonstrate how to accentuate data visualization of performance patterns within the multi-tiered systems of supports. Key takeaways include staff leveraging of the data warehouse, pattern identification, teacher training best practices, loose and tight team oversight, PLC frameworks and continuous improvement cycle templates. Fostering strong collective efficacy of teachers can help improve school districts’ student performance outcomes!
