St Brigid's J.N.S. is a mixed Junior school with classes from Junior Infants to Second class.
The school was opened in 1982 and was originally located in Aylesbury. The chilldren were transported by bus to and from the temporary school each day. Tom Walshe was principal and teaching staff were Jacinta Mitchell, Treasa Ni Cheannaigh and Larry Burke.
