Students at Montera Middle School in Oakland said the school's eighth-grade class was full of "drama" earlier this year. There had been a fight between two girls, and the conflict had broadened to the girls' friends. Some students "were coming to school in sweats, ready to fight," recalled Yari Ojeda-Sandel, a staffer at Montera who coordinates the school's new conflict-resolution program known as restorative justice.
