I would argue that we have a generation of young people, particularly minorities, who are no longer putting up with the kinds of things their parents put up with. They're much more self-confident. It's no longer acceptable to make fun of people because of race or sex. But it has always been present in American society.
We know the parental support, community support, makes a difference. It's not just the metrics of testing and putting pressure on the schools and on the teachers.
