Scoil Mhuire in Buncrana has received approval for emergency works.
Education Minister Joe McHugh has confirmed that necessary electrical works will be carried out at the school on St Oran's Road this year.
Fine Gael County Councillor Mickey Doherty said: “Another important project is getting the green light. That’s good for the school and good for local contractors and businesses.
“More than 20 emergency works projects have been approved by the Building Unit for schools in Donegal since the start of last year. I look forward to seeing work progress and hearing about more.”
Fine Gael candidate for Donegal County Council Michelle McKenna added: “This is great news for one of our Buncrana schools and I am delighted that Minister McHugh is in a position to make so many announcements for school building work in the country and across Donegal.”
