Ballyfermot parents have said that they are "worried sick" over their children being segregated later this year when three local secondary schools are set to combine.
It has been proposed by the Department of Education that St Dominic's, St Carita's and St John's secondary schools amalgamate into one building at St Seton's in Ballyfermot in September.
Funding for the new school building was approved in February 2021 by the Department of Education.
