Both the junior and senior school at Scoil Chaitríona Cailíní in Coolock are to remain closed for the rest of the week following a fire early this morning.
The Department of Education has said a number of options for accommodating students are currently being examined.
They include using classrooms in local schools and putting prefabs on site.
A decision by the school's board of management on what options to pursue is expected to be made next week.
The school was severely damaged in this morning's fire with the roof of the senior side of the school collapsing.
A number of classrooms on the first floor have been gutted by the blaze, which tore through the building at around 6am.
A local resident alerted Dublin Fire Brigade after seeing smoke coming from the school, which is located off the Malahide Road near Mask Avenue.
Dublin Fire Brigade said it brought the blaze quickly under control and six fire tenders went to the scene, including a specialist unit.
One local resident was taken to hospital as a precaution as a result of smoke inhalation.
Dublin Fire Brigade said the damage was limited to the senior side of the school.
A garda investigation into the cause of the fire is under way.
