Ohio's public schools provide special education services to children with disabilities as early as preschool. Every year, as required by Ohio Revised Code 3323.20, the Ohio Department of Education and Workforce reports the number of preschool children who received state-funded special education services during the previous year, disaggregated according to each area of developmental deficiency identified by the Department for the evaluation of such children. The 2022-2023 school year had an overall increase of 2,660 (10.6%) preschool-age children receiving special education services compared to the prior year.
