"The whole purpose of federal law and state law should be to help schools improve, not to come in and close them down and say, 'We're going to start with a clean slate,' because there's no guarantee that the clean slate's going to be better than the old slate," says Ravitch. "Most of the schools that will be closed are in poor or minority communities where large numbers of children are very poor and large numbers of children don't speak English. They have high needs. They come from all kinds of difficult circumstances and they need help — they don't need their school closed."
