From the National Center for Education Statistics, Report on the Condition of Education 2022
From school year 2009–10 through 2020–21, the percentage of public school students served by the Individuals with Disabilities Education Act (IDEA) increased from 13 percent (6.5 million students) to 15 percent (7.2 million students) In 2020–21, some 33 percent of all students who received special education services had specific learning disabilities, 19 percent had speech or language impairments, and 15 percent had other health impairments (figure 6) (Students With Disabilities).
