80 percent of schools could be labeled as failing under NCLB

From The New York Times: More than 80,000 of the nation’s 100,000 public schools could be labeled as failing under the No Child Left Behind Act, U.S. Secretary of Education Arne Duncan says. The estimate, based on an analysis of testing trends and the workings of the law’s pass-fail school rating system, is the latest evidence of the law’s shortcomings and the need to overhaul it, Duncan says. Even many of the nation’s best-run schools are likely to fall short of the law’s rapidly rising standardized testing targets.
