MASS school closures in Orange are considered unlikely as the state fights the spread of coronavirus.
The Catholic Diocese of Bathurst, which governs Saint Mary's and Catherine McAuley Catholic primary schools, as well as James Sheahan Catholic High School, has told parents strategies were continually re-assessed.
Schools executive director Christina Trimble said mass school closures were "unlikely" in current advice.
"Schools should not unilaterally close - even with the diagnosis of the first child - unless they are directed to do so by NSW Health," she said.
"Closures to date have been for short periods [of one to two] days while an assessment of contacts has been made by NSW Health."
She said schools had increased their vigilance around hygiene and staff and students had been urged to remain at home if they had cold and flu symptoms.
"If a student or family member tests positive to COVID-19 they are requested to contact their school principal," she said.
James Sheahan Catholic High School has cancelled a disco on Wednesday.
Orange Anglican Grammar School principal Louis Stringer said the school had decided to withdraw from unnecessary travel to locations where there were current recorded cases of COVID-19.
He said the Sydney Urban Challenge for years 8 and 10 was being rescheduled while seeking alternative programs.
"Mercifully, the current data demonstrates that while children are readily infected, they tend to recover quickly and strongly," he said.
"Not so the elderly and it is our intention to both protect the students in our care from infection, but equally so, the more elderly in our community from contact with students who may have travelled to areas where known infections have taken place."
Mr Stringer said a closure would only occur if a case was confirmed on campus.
"The school has available alternative educational delivery methods to support teaching and learning should this event arise," he said.
"This will ensure that students can access individualised ongoing lesson content, even when distanced from the physical campus due to personal illness, or a temporary school closure."
Mr Stringer has urged parents to consider care arrangements in the event of a temporary closure.
Kinross Wolaroi School decided late on Thursday to suspend all non-essential teaching and learning events, including activities involving having students and staff in close contact with others for longer than two hours or in large numbers.
The list included, excursions outside the local area, visits from people outside the school, community events including this weekend's Alumni Reunion, weekly assemblies and off-campus professional learning for teachers.
The school requested no hand shaking at a recent parent/teacher night and throughout the school.
The school confirmed if a boarding student was recommended for exclusion, they would be accommodated in an alternate location until their parents could collect them.
Principal Dr Andrew Parry said it seemed certain the virus would "make its way to us in time".
"The school considers that we should now take further steps to promote 'social distancing' for the protection of students, staff and our community by restricting contact between students, other schools and the outside community," he said.
"Our teaching and learning team have begun preparing for potential disruption to student learning."
For those educated in music after school hours, Orange Regional Conservatorium has told parents there would be no interruption to planned lessons, ensembles and groups or concerts.
In an email to parents, the conservatorium indicated door handle, tabletops, light switches and shared instruments, such as pianos, were routinely cleaned.
The NSW Department of Education did not respond to a request for comment by the time of publication, but did point to online advice halting international travel for public school students and guidance on hand washing.
