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.
The latest report from the New York City Charter Schools Evaluation Project compares the academic performance of charter school students with that of their peers who attempted to enroll in charter schools but were not selected in a random lottery. This method allows the researchers to isolate the effect of attending a charter school, without being concerned that factors related to the decision to apply to a charter school are really driving achievement differences.
