Education Week reports that Secretary of Education Arne Duncan has tightened the screws on states and districts that get a waiver from NCLB issued by him.

They must comply with his interpretation of teacher quality and must reaffirm their commitment to Common Core (“college=and-career-readiness standards”), while upping the ante on accountability.

Based on his experience in Chicago, Duncan seems certain that more carrots and more sticks will do the trick.

The waivers enable him to impose Race to the Top requirements on every state, even those that won no money at all.
