Over 100 students from the new secondary school in An Daingean, Co Kerry, refused to go into their classrooms today.
The students remained outside Pobalscoil Chorca Dhuibhne throughout the day in protest at the school's all-Irish policy.
The students claim that their education is suffering because some of them are not fully competent in the Irish language.
The principal of the school, Padraig Firtéar, said today that he was very disappointed with the students' action and that only a few had approached him on the issue in advance.
The controversial policy has been the subject of several heated public meetings in the town.
Attempts are being made to resolve the matter, but meanwhile the students say that they will continue their protest tomorrow.
