Public charter schools could theoretically experience fewer school climate problems than district-run public schools because of additional competitive pressures, autonomy, and improved matches between schools and students. Using publicly available data from the New York State Education Department, I analyze differences in 13 school climate problems between public charter school and district-run public school sectors. After controlling for observable differences in students and schools between sectors, I find that public charter schools tend to report fewer school climate problems than district-run public schools in New York state in the 2017-18 school year. Specifically, public charter schools report fewer assaults with physical injuries, assaults with serious physical injuries, forcible sex offenses, other sex offenses, weapons possessions resulting from routine security checks, other weapons possessions, and false alarms than district-run public schools; however, public charter schools tend to report more cyberbullying than district-run public schools. The charter school climate advantages tend to be more pronounced in New York City than the rest of the state.
