A survey has revealed more than one third of school principals have been attacked by a student or parent in 2018.

The survey, run by the Australian Catholic University, has determined that in Queensland, violence against principals increased from 27.9 per cent in 2011 to 36 per cent in 2018.

ACU psychologist Associate Professor Philip Riley, says, “The steadily increasing levels of offensive behaviour in schools of all types is a disgrace and it needs to stop.”
