Children as young as five with disabilities are being secluded and restrained at school.
A new report from Inclusion Ireland highlights 14 cases, one involves a child being left unsupervised in seclusion for long periods despite a history of seizures.
The charity says that a lack of available research on the subject means the number of cases of restraint, isolation and seclusion could be even higher.
They are calling on the Government to act and spokesperson, Mark O'Connor, has said there are a number of key areas which need to be looked at.
Mr O'Connor said: "Regulation, inspection and monitoring of this issue. Currently, as we stand, there is no need for a school to report anything.
"Training for staff so that these incidents are reduced to the absolute minimum and then the appropriate services for children.
"Child and adolescent mental health services, speech and language therapy, psychology, all of those types of services should be immediately available to a child who is experiencing these situations."
