Overall school climate results: distribution of disciplinary events throughout school networks, comparing treatment, and control schools. Visualization of the effect of treatment on disciplinary reports of peer conflict among the 49 schools that provided administrative data (26 in control, 23 in treatment). Color coding reveals the average number of times each student in the school was disciplined for peer conflict, from dark blue (little conflict) to dark orange (many disciplinary events; higher concentration of dark oranges among control schools). Student nodes are colored red when the student was disciplined for conflict, and their node is scaled to the number of times they were disciplined during the year.
