The U.S. Department of Education is expected to announce Friday that Washington and Wisconsin have been granted waivers releasing them from the obligations of No Child Left Behind, President George W. Bush's key education legislation. These are just the latest states to be let off the hook from the law's most demanding conditions. The Obama administration has given over half the states in the country a pass from the legislation's general provisions in the past five months. "The more waivers there are, the less there really is a law, right?" suggested Andy Porter, dean of the University of Pennsylvania's graduate school of education.
