22 schools are expected to have safety measures in place in time for class this morning - as the schools building controversy continues.
One school building will remain closed at phase 1 of the Ardgillan Community College in Dublin - and 19 schools have been cleared to open fully.
Work continued late into the night as teams rushed to complete the required precautionary measures recommended following structural assessments on schools constructed by Western Building Systems.
The Department of Education says five teams involving over 250 workers have been on site through the weekend to facilitate the reopening of schools this morning.
Students were heading for bed as the Department issued their latest update, that 19 schools had been cleared to open
A Department source says school principals have been kept informed of progress throughout - and parents are being contacted by their school authorities directly, about local arrangements.
Sinn Féin Councillor Paul Donnelly has been speaking to parents in Tyrrelstown in West Dublin and he says it is a difficult situation for parents and children.
"There's just so many issues that have to be addressed," said Mr Donnelly.
"There's safety issues, there's the bus issues, there's transport... It is a really difficult situation for everybody.
"Tyrrelstown is a brilliant community and I know that they are pulling together as much as they can but there is no doubt about it, there are huge concerns still"
