Test scores improved for students with disabilities from 2005-06 to 207-08, according to a new study by the Center on Education Policy.
The study found that students with disabilities showed progress at all levels of proficiency in 4th grade, where the median percentage scoring at the basic level or above was 71 percent. Most states showed more gains than declines among students with disabilities over the three-year period.
No Child Left Behind was a “strong factor” in the gains, said Jack Jennings, CEP president.
It’s difficult to evaluate disabled students’ progress, CEP said, because of “the often-rapid changes in the number of test-takers that some states reported in that subgroup from year to year” and changes in how many students take alternate assessments rather than the regular state exam.
Despite the progress, the gap between disabled and mainstream students remains wide.
