This study examines the association between schools and student bullying behaviors and victimization among a nationally representative sample (N = 9,107) of New Zealand high school students. In particular, the study sought to explore the role of characteristics of schools and school culture with respect to bystander behavior, while controlling for individual student factors related to victimization and bullying behaviors. Results indicated that a total of 6% of students report being bullied weekly or more often and 5% of students reported bullying other students at least weekly. Results of multilevel analyses suggested that schools characterized by students taking action to stop bullying were associated with less victimization and less reported bullying among students. In contrast, in schools where students reported teachers take action to stop bullying, there was no decline in victimization or bullying. Overall, these findings support whole-school approaches that aid students to take action to stop bullying.
