Very few students continue to physically attend Junee's schools, with NSW Premier Gladys Berejiklian encouraging parents to keep their children at home where possible.

The NSW education department has said no child will be turned away from school, with supervision provided for children of essential workers who continue to attend.

The department has given public school principals authority to support as many staff as possible to work from home.

Junee High School principal Scott Frasier said he had been impressed with the work by students, staff and parents to adapt to the new normal.

The school is currently offering online learning through Google Classroom and Microsoft Teams, as well as take-home hard copy booklets of work, and Mr Frasier said students were able to choose what options worked best.

"These weeks have been just some trialing weeks about what works at the family home, what works for them as a learner so its been a really big opportunity for these kids to discover themselves as learners away from the school environment and still focus on learning," he said.

"Some kids have really enjoyed not getting up right on time in uniform and working hard, and other students are really missing the social aspects, the discussion in the classrooms and have been getting involved in those discussions online."

Mr Frasier said the school had been getting strong feedback from parents who were actively engaged in helping their children adjust.

He said he had also heard stories of older students helping younger siblings.

"That's been really impressive to hear how great our kids are at helping their younger brothers and sisters," he said.

Mr Frasier said it was difficult to predict how the rest of the year would play out, but while the school was still waiting on advice around some of the more practical senior classes, Year 12 students had been assured they would get a credential at the end of the year.

He said the Year 12 cohort had adapted well to online classrooms and taking their mid-term exams from the comfort of their own home, which teachers will mark and provide feedback on.

"Because they're non-assessable the students will be able to use that feedback really well and it hasn't been impacted by them doing it offsite," Mr Frasier said.

Mr Frasier said for students learning from home, his main advice was to maintain a daily routine incorporating socialisation and exercise.

He said students should also take the opportunity to spend some time developing other skills such as practicing a musical instrument.

"People have got more time in a sense now there's less transport or travel ... using their time efficiently and effectively there also frees up some time for some of those other important things that they'd like," he said.
