St. Mary’s College Junior School
Welcome to St. Mary’s College Junior School

We are a Catholic school, welcoming children of all faiths and none. Our aim is to promote the whole development of the child: intellectually, physically, culturally, morally and spiritually.

We cater for boys from Junior Infants to 6th class, ensuring community is an essential part of the education we offer. Our parents are an integral part of that community, working with and for the good of the School, promoting a learning community of child, parent and teacher.

Our Junior School motto is ‘We are all different but equal’ respecting the right of every child to feel happy, safe and included within the St. Mary’s community.

Our aim is that by 6th Class, each boy, regardless of his ability, is proud of his achievements and ready for the transition to secondary school.
