"The anniversary of the signing of the No Child Left Behind last Friday reminded me that my long support for that landmark bipartisan law needs revision. The law has served its purpose. Instead of amending it, as the Obama administration and the Congress seem likely to do, let's dump it and try something different.I wouldn't make such a radical suggestion if I didn't think the law's main elements would survive without it. All the states have been forced to establish annual testing that identifies which schools are not serving their students, particularly those with family and personal disadvantages. Any politician who tries to junk those tests is going to lose the next election to an opponent who asks the simple question: 'Don't you think our schools should be accountable?'"
