Tougher standards have left more Michigan schools failing to meet requirements of the federal No Child Left Behind law.
Michigan education officials said today that 21 percent of the state's public school buildings failed to make adequate yearly progress as defined by the law in the 2010-11 academic year. That's up from about 14 percent in the previous academic year.
The decline in the number of schools meeting standards comes even though state test scores have been on the rise. Higher proficiency targets are now required under the federal law.
