State law requires that Ohio's superintendent of public instruction to report on the status of implementation of special education and related services for children with disabilities. This includes the number of children identified with disabilities and the number of identified children receiving services. The Ohio Department of Education collects this data through the Education Management Information System (EMIS). This report is based on data gathered from EMIS. Students with disabilities account for 15.2 percent of all Ohio's preschool and school-aged students, which include all children ages 3 through 5 and 6 through 21, respectively. As of Oct. 31, 2017, there were 270,142 students reported to the Ohio Department of Education who were identified with disabilities and eligible to receive special education services or related services. In the 2017-2018 school year, 266,671 eligible students received services, amounting to 98.72 percent of all students identified as eligible for special education being served.
