The children’s commissioner is to investigate the education of children with special educational needs (SEN).
Koulla Yiasouma said her office would look into how decisions on the schooling of SEN children were made.
She made the comments after a mother told the BBC that her autistic son had not been to school for six months.
Ruth McClure said the Education Authority (EA) had not been able to find a suitable place for him.
In response, the EA said it was committed to meeting the assessed needs of individual children.
