Confidence teachers will be able to navigate the issues around mask wearing at schools.
It's recommended for over 12s but not required, when school begins for most of the country on Thursday.
Clinical psychologist Dougal Sutherland told Kate Hawkesby schools should make a clear decision about mask-wearing, with exceptions for children with communication difficulties.
He says it could be a bit tricky because of peer pressure.
"I think, though, we should have faith in our teaching staff. Teachers, their job is to engage kids, they know how to engage kids in learning and, yes, this is another barrier, but actually these guys are professionals."
