A state review shows that in one year in the Columbus school district, 371 disabled children were held down, physically removed from a class or put in closet-like rooms to calm them down.
The Columbus Dispatch reports that the review offers insight into the children's behavioral problems and how workers try to manage them.
The numbers are the result of a state review in response to a complaint from a group called Disability Rights Ohio, filed with the Ohio Department of Education in November.
The district previously refused to release those figures, saying they were private.
Investigators cleared the district because no child spent what amounted to 10 school days in seclusion. The state reviewed district records from November 2011 to November 2012 but didn't observe classrooms or interview parents, students or teachers.
