Students with disabilities, even as their graduation rates inch upwards, a new report finds.
In 2012-13, students with disabilities scored from 32 to 41 percentage points lower than their peers on state tests, according to the report, released last month.
The gap was lowest in elementary mathematics, and highest for middle school reading.
The report, by the National Center for Educational Outcomes at the University of Minnesota, shows that gaps between students with disabilities and their peers have barely budged from 2006-07 to 2012-13.
