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.
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.
