As students head back to school this week, violence will follow a sizable number of them. Roughly 13 percent of public high school students report having had a fight on school property during the past school year. About 8 percent say that they were threatened or injured with a weapon at school, and 7 percent were bullied.
In some schools, however, a variety of violence-prevention programs have fostered substantial reductions in violent and disruptive behaviors, according to two new, independent research reviews. This positive effect occurs in all grades, from prekindergarten through high school, and in all schools, from the poorest to the wealthiest.
