Cavan's Gaelscoil Bhreifne has applied for planning permission for new ASD classrooms.
It's part of a planned project which would see a number of upgrades carried out at the school.
Management hopes to build a new single story extension, which would include two ASD classrooms, a mainstream classroom, office link corridor and toilets.
The school moved to the former St Clare's Convent site in Tullacmongan in Cavan town in 2018.
