A Dublin post-primary school has received just one application for three full-time Irish teaching positions it has advertised for.
Hansfield Educate Together Secondary School is growing rapidly to cater for a burgeoning local young population in Dublin 15.
While 38 Leaving Certificate students are graduating from the school this week, up to 190 children will begin First Year at Hansfield next September. That is a fivefold increase.
School principal Bernie Judge says she needs to employ "at least ten new teachers" to meet the school's growth".
She added: "And that's not including any of my current teachers who may decide to leave".
The school advertised recently for teachers.
As well as receiving just one application for the three Irish teacher jobs, it received just one applicant for two Technology posts, and one applicant also for the job of special needs teacher in its Autism unit.
The school has vacancies in a wide range of other subjects, including English, Maths, Art, Business, Geography, History, Home Economics, PE, Science, and Guidance.
The school will hold interviews, but will also now re-advertise for Irish teachers as well as some other positions.
"The worry is that we won't have enough qualified experienced teachers to deliver the curriculum," Ms Judge says.
Referring the shortage of Irish language teachers, she said: "We are really concerned right now that we won't have enough teachers to be able to offer Irish classes to all the students".
Ms Judge says a shortage of teaching graduates, the cost of teacher education, and issues related to low pay and the cost of accommodation are contributing to the teacher shortage.
She says in some cases schools cannot offer young teachers a full hours post, and that this is acting as a disincentive.
Department officials will meet teacher trade unions and school management representatives in Dublin tomorrow as part of ongoing efforts to address the shortage.
