Stormont Education Minister Peter Weir says there are no plans for the mandatory wearing of face coverings when pupils return to classrooms next month.
Speaking during an online meeting of the Northern Ireland Youth Forum yesterday, Mr Weir said other hygiene measures would be in place to mitigate the risk of coronavirus spreading within schools.
"The indications are that for both pupils and, to a large extent teachers, PPE equipment isn't necessary," he said.
"While a lot of things are very uncertain about the virus, the level of direct danger to young people is very, very low.
"Therefore at the moment it doesn't look as though the mandatory wearing of masks will be needed."
Primary and post-primary schools will reopen for staff from August 17, and for priority groups of pupils from August 24.
The Department of Education has said this phased reopening of schools is "subject to medical and scientific advice", and that for most pupils it will involve "a schedule with a mixture of school attendance and remote learning at home".
But Justin McCamphill of the NASUWT union has urged ministers to consider making face masks compulsory for children in all secondary schools.
Mr McCamphill highlighted recent changes in Government guidelines on face masks in shops and on public transport to make the case that similar changes should apply in post-primary schools.
"The current guidance on masks is meant to be dynamic and take account of the changing infection rates and scientific updates," he said.
"If you have to wear a mask in a supermarket or on the school bus, what is the difference when it comes to schools?
"If masks are now being recommended in these instances we would expect schools to be treated the same.
"The medical advice and infection rates are going to change all the time and decisions around masks in schools will have to be made at the last minute."
Meanwhile, Children's Commissioner Koulla Yiasouma says a Department of Education proposal to isolate pupils who have symptoms of coronavirus "behind a closed door" is worrying.
Ms Yiasouma was referring to the department's reopening guidance for schools, which states that a child awaiting collection "should be moved, if possible, to a room where they can be isolated behind a closed door" while "appropriate adult supervision should be provided as required".
The guidance adds: "Ideally, a window should be opened for ventilation. If it is not possible to isolate the child, move them to an area which is at least 2m away from other people.
"A risk assessment should be undertaken by the school to address this."
Ms Yiasouma said: "It is never appropriate to isolate a child 'behind a closed door', never mind when they may be feeling unwell.
"I fully accept that schools must take reasonable precautions in order to protect all children and staff, but these should be proportionate.
"I was assured by officials in June that this part of the guidance would clearly advise children who were displaying symptoms of Covid-19 would be treated with dignity. As it stands, the guidance does not do this.
"I have written to the minister and made it clear that he must remind all schools of their responsibility to take the health, wellbeing and best interests of the child and young person into account."
