Four teachers, including the principal of a regional New South Wales school, have pleaded not guilty to assaulting two students.

NSW police allege the teachers assaulted the boys at school between August 2024 and June 2025.

A man and two women are facing one charge each of common assault against one of the boys in separate incidents. Police allege the incidents occurred between February and June 2025.

Another man is separately charged with assaulting one of the boys on two separate occasions in September 2024 and again between May and June 2025. The man is also charged with common assault against another boy in August 2024.

Lawyers for the accused teachers entered not guilty pleas for all four in Queanbeyan local court on Tuesday. The teachers did not appear in person.

NSW police announced the charges in March as part of a joint investigation between community justice in Queanbeyan and the NSW education department.

The names of the teachers and the school involved cannot be published for legal reasons. Police said none of the teachers on bail was currently working at the school.

The education department previously said in a statement that while the exact nature of the assaults was not known, the allegations were deeply concerning.

“Behaviour of this kind is unacceptable in any school,” a spokesperson said.

The case was expected to return to court in June.
