What is Data Driven Decision Making?Collected data identifies strengths of learning and obstacles to student learning and determine which research-based instructional strategies will best address their students and learning objectives. At the grade or content level, teachers collaboratively analyze data from multiple data sources that include District Benchmarks, State Assessments, and other common formative assessments. Teachers meet as ‘Data Teams’ and analyze the effectiveness of the instructional strategies selected and implemented at the previous data team meetings by examining student performance data that was measured using common assessments. Data Teams occur on district, school, grade and/or content levels. School and District Data Teams are also used to develop and monitor improvement.
