Education Secretary Arne Duncan says an estimated 82 percent of U.S. schools could be labeled as "failing" under the nation's No Child Left Behind Act this year.
Under the Education Department's calculation released Wednesday, the number of schools not meeting targets will skyrocket from 37 to 82 percent in 2011. The schools will face sanctions ranging from offering tutoring to closing their doors.
Duncan is expected to testify at a House education and work force committee hearing Wednesday afternoon, asking federal lawmakers to rewrite the Bush-era act, which was established in 2002.
The targets were designed with the goal of having all students proficient in math and reading by 2014.
