Anti-cyberbullying lessons should be introduced in primary and secondary schools, a confidential report to cabinet recommends.
The recommendation comes after a new EU study shows that Irish children are the most likely in Europe to experience some form of cyber-bullying.
Director of the anti-bullying centre at DCU James O'Higgins Gorman said they had been calling for measures to be taught in schools for some time.
"In the old days, young people would have been educated in social etiquette so they can make their way in society," he said.
"We need the same thing today in relation to the cyber world - the internet - because young people today live in that world."
