A new campaign group is holding a public meeting to highlight the growing demand for an Educate Together second-level school in Dublin city.
Over 2,000 expressions of interest have been collected from parents who are looking for an addition to the current second-level school provision.
The Dublin City Educate Together Second-level Action Group has called on the Government to establish such a school as soon as possible.
However, the Department of Education says that currently the demographic demand for a new second-level school in Dublin is not there.
Speaking on RTÉ's Morning Ireland, Educate Together CEO Paul Rowe said there are a large number of schools in the greater city of Dublin area which are undersubscribed.
"The case that the department makes is that in established areas there are plenty of school places, the question is now to allocate school places to the type of schools that parents actually want," Mr Rowe said.
The first Educate Together second-level schools will open in September 2014.
They will be Ballymakenny College in Drogheda, Co Louth; Hansfield Educate Together Secondary School in Blanchardstown West, Dublin 15; and Kishogue Community College in Lucan in Co Dublin.
Mr Rowe said secondary education is in need of serious reform.
He added that the ethos and the approach to learning in Educate Together secondary schools will be significantly different to what is currently on offer.
