An increasing number of American students are reportedly utilizing special education services in the nation’s public schools.

The number of students ages 6 to 21 covered by the Individuals with Disabilities Education Act grew to 5.83 million in the fall of 2014, the most recent year for which statistics are available.

By contrast, just three years earlier, that count was at 5.67 million, according to an analysis of U.S. Department of Education data conducted by Education Week.
