SYDNEY, Oct 10 - Documents obtained under Freedom of Information reveal the department is investigating 246 complaints of alleged abuse of children with disabilities, with alleged perpetrators including teachers, teacher's aides and volunteers, ABC's 7.30 reported on Monday night.
"These shocking alleged abuse cases are on this government's watch - and it needs to act immediately," opposition disability services spokeswoman Sophie Cotsis said in a statement on Tuesday.
Caroline Franks' 16-year-old son, Austin, is autistic, non-verbal and has an intellectual disability.
Franks told the ABC her son was abused at Pennant Hills High School.
"He would come home covered in blood ... he was being pushed around with boxing batons or was screamed at or not allowed to go to the toilet," the mother said.
"Nobody wants to see their child hurt. A school is supposed to be a safe environment."
Education Minister Rob Stokes told the ABC "it shouldn't have got to a position where there needed to be that sort of device used in a classroom".
Comment has been sought from the NSW education department.
