Stormont Executive agrees timetable for full school return in NI
Education minister wants all children back in school by 12 April
Education Minister Peter Weir said it was a "very good day" for education in Northern Ireland and "another important step forward for schools, pupils and parents".
"This is a significant milestone in the return to a normalised educational environment," he said.
Mr Weir said his focus was now on developing plans to help children catch up on what they had missed out on during lockdown.
He said he would be bringing proposals to the Executive that included a wide range of summer school provision.
Covid testing
As part of plans to return to classroom learning, Covid-19 lateral flow testing is being introduced for teachers and some older pupils.
The tests will be offered to staff in nurseries, pre-schools, primary schools and secondary schools and to pupils in year groups 12-14.
The tests are being introduced in a phased basis. They are being trialled and demonstrated in secondary schools this week ahead of a full rollout to other educational settings after the Easter holidays from 12 April.
From that date there will be an expectation that year group 12-14 pupils will take the tests at home.
The timetable for returning to school was agreed by Stormont ministers last week as part of the initial steps of their lockdown exit strategy.

The Executive has also amended regulations around elite sports to enable two World Cup qualification matches scheduled for March 25 and 31 to take place as well as a friendly match between Northern Ireland and the US on March 28.
No spectators will be permitted at any sporting event.
The 12 April easements are subject to final ratification by the Executive in the week before they come into effect, likely on April 8.
The death of one further patient who had previously tested positive for Covid-19 was reported on Sunday by Northern Ireland's Department of Health.
Another 125 cases of the virus were also confirmed.
