Parents of pupils of at Coláiste Lú in Dundalk, Co Louth have said today they have no choice but to take a High Court action to get their children an education through Irish.
Students at the school, which is described as a "Irish medium-unit" staged a walkout from their classrooms last week.
Parents say they are concerned at the reduction in subjects being taught through Irish and the impact it is having on students, particularly those preparing for state exams.
Coláiste Lú is an Irish medium unit - or aonad - at the larger English-medium Coláiste Chú Chulainn.
Units like this are established where the Department of Education has determined it is not feasible to establish a stand-alone Irish medium secondary school but where demand does exist for some Irish-medium provision.
In a statement today parents say they have been left with "no choice" but to file an application to the High Court in a fight for the right for students of Coláiste Lú to continue to receive Irish medium education.
It said Louth and Meath Education and Training Board has yet to issue a response to their protest and petition.
Last week the LMETB said "similar to other schools nationally", it has experienced difficulty in securing teachers in certain subject areas.
