Here's a proposal that will really leave no children left behind.

Instead of having children adapt to school, Levine urges schools to make accommodations for the rich variety of minds they face. Schools, he says, should reduce the amount of memorization required (many, many children have memory difficulties), not insist on speed at the expense of thoughtfulness, allow students multiple options for evaluation (not just traditional tests) and recognize that treating kids fairly does not mean treating them all the same way.
