This study shows how high-performing school systems use data to improve instruction for elementary students. In this report, the work of four school systems that were identified as leaders in data-driven decision making are captured. This study included two mid-size urban school districts and two nonprofit charter management organizations (CMOs). All of these school systems have records of improving student achievement over time.
After the quality of a school’s teachers, the quality of a school’s leaders is the most influential school-based factor affecting student learning. Moreover, research has found that leadership impacts student achievement the most in academic settings serving students who traditionally have not done well in school.
