Students will return to school one day a week from May 11 and teachers will be given priority access to coronavirus testing, as confirmed by Premier Gladys Berejiklian.
The goal will be to have all children back at school full time by term 3.
NSW Education Minister Sarah Mitchell said schools should aim to have about a quarter of students on campus each day from May 11, "but how they break that group up will be a matter for them".
"We are asking [schools] to certainly consider family groupings, keeping siblings together, so that that will make it a lot easier for parents as we transition back to normal schooling," Ms Mitchell said.
"We'll also be asking parents to stagger drop-off and pick-up times, and recess and lunch breaks within our schools. We think that these are important measures in line with health advice that will ensure that everybody feels safe in their school environment.”
