The most common disabilities among public school children are part of a category called specific learning disabilities, which includes dyslexia, dysgraphia and dyscalculia. “This is another area where I think that the data should be ringing real alarm bells for us, especially for our high school-age students with disabilities,” Coco says. Roughly 12 percent of students with disabilities in traditional public schools took the SAT or ACT in 2021-22 compared with 20 percent of non-disabled students. These gaps were smaller in charter schools than in traditional public schools. They made up 13 percent of traditional public school students with disabilities and nearly 15 percent of charter school students with disabilities in 2021-22.
