The U.S. Department of Education's latest move to grant more flexibility under the No Child Left Behind Act, this time aimed at helping schools that narrowly miss the law's requirement for high participation on standardized tests, was generally welcomed. The appetite for further adjustments appears to be growing. The new policy allows states to average participation rates for a given school over two or three years if that school misses the federal threshold in its most recent testing. It also permits a student to be excluded from a school's calculation in the case of a serious medical emergency.
