Abstract: The use of network-based continuous improvement (CI) in education has grown substantially in recent years. The Gates Foundation invested in networked-based CI from 2018 to 2025 by awarding more than $300 million to intermediary organizations that led 34 Networks for School Improvement (NSI) across the country. This is the appendix to the full report, which describes the effect of the NSI initiative on student outcomes through schools' fourth year of participation and explores the aspects of implementation that may have contributed to its effects. The study measured the effect of the NSI by comparing outcomes for students in NSI schools to similar students in comparable schools that did not participate in the initiative. The appendices include: (1) Additional Details for the Impact Analysis: Study Design, Data, and Analysis Methods; (2) Additional Details About the Impact Analysis Study Findings; (3) Additional Details for the Correlational Analysis: Data, Sample, Measures, and Analysis Methods; (4) Additional Details About the Correlational Analysis Findings; (5) List of Intermediaries and Networks in the NSI Initiative; and (6) Glossary.
