Education Minister Sue Ellery said the tough new measures were aimed at cleaning up violence in schools and were part of a range of tactics now available to principals and teachers to manage incidents and tackle problem behaviour.

Alternative learning settings to help students manage their behaviour would also be trialled, including support programs to help change behaviour.
