The schools are categorised under the Gundagai region, in which there were only five reports of assaults recorded between January 29 and August 31, 2019.

There are 478 students enrolled at Junee's public schools.

Comparatively, Wagga's public schools were among the worst in the state.

There has been up to 60 assaults in Wagga's schools, including up to 10 instances of students behaving violently toward teachers.

The Department of Education was questioned on what its definition of an "assault" in the school grounds would constitute, but did not offer an explanation.

However, the School Community Charter expands the definition of unacceptable behaviour occasioning school-based punishment to include aggression, threats, obscenity, and intimidation.

"There is a zero-tolerance policy in NSW public schools when it comes to violence, bullying, harassment or assault of any kind," a spokesperson for the department said.

"Principals will take strong action when inappropriate behaviour interferes with the safety of the school community."

Acting president of the NSW Secondary Principals' Council, Craig Petersen, said addressing the problem takes recognising the root cause.

"There's no simple answer, part of it is to do with the portrayal of violence in society," Mr Petersen said.

"It models to our kids that we deal with conflict by being aggressive, and we need to call that out."

A Department of Education spokesperson confirmed its commitment to supporting school staff in managing student behaviour.

"Any student involved in violence or who engages in criminal behaviour at school may be suspended and their parents are notified. Police are also informed if necessary," the spokesperson said.

"If incidents do occur, the Department's Incident Support Unit, which includes seconded NSW Police officers, co-ordinates support and advice to schools."
