Principal’s Welcome

Jenny Costello, Principal

St Tiernan’s Community School, adjoining beautiful parkland, is located between Dundrum and Sandyford, offers a wide range of subjects, academic and practical, in a multi-denominational setting.

Serving the communities of Balally, Dundrum, Sandyford and the surrounding areas for over 40 years, we have a strong tradition of providing an educational environment that is safe, welcoming and respectful. Our staff of dedicated professionals are deeply committed to bringing out the best in each and every student. We work in partnership with parents and the community to provide a broad curriculum that aims to meet the needs of all our students.

In St Tiernan’s learning is enjoyable, challenging and supported. Our students are encouraged to become incredible thinkers, leaders, friends, and local and global citizens who practice inclusivity. With that in mind, we provide a stimulating education that encourages deep thinking and builds confidence, resilience and highly motivated learners and leaders in school and the community.

Complementing that, we have an extensive range of extracurricular activities to foster friendship, teamwork, sports, the arts, community and ecology. Our new, state-of-the art Sports Hall with a fully equipped gym, and our full size All Weather Pitch, are enjoyed by our students every day and provide many opportunities to participate in multiple sports. Our school musicals are highly anticipated, enjoyed by all in our community and offer students a platform to develop their talents. Our interior courtyards provide a wonderful space for students to enjoy the outdoors during the day and develop their understanding and appreciation of the natural environment.

We foster the moral development of students through a school ethos based on respect for the dignity of each individual. We are alert and sensitive to the needs of students and expectations of society in a constantly changing world and we are innovative in modifying and designing programs to meet these needs and expectations. Most importantly, we encourage students and parents to become fully involved in the social, cultural, religious, intellectual and sporting life of the school community. 

Our school motto is:
Coigil Aithinne D’Aislinge

which translates into:
Follow Your Dreams

In St Tiernan’s your child will receive an education that will enable and encourage them to reach their full potential and follow their dreams in a caring and welcoming environment. We look forward to supporting your child on their journey with us and giving them a school experience filled with friendship, learning and many treasured memories.
