Bullying Prevention: Tips for Teachers, Principals, and Parents | Edutopia:
"Approximately 32 percent of students report being bullied at school. Bullied students are more likely to take a weapon to school, get involved in physical fights, and suffer from anxiety and depression, health problems, and mental health problems. They suffer academically (especially high-achieving black and Latino students). And research suggests that schools where students report a more severe bullying climate score worse on standardized assessments than schools with a better climate."
