Principal’s Welcome
Welcome to the website of Holy Trinity N.S., a school catering for the needs of families living in the parish area of Sandyford, Dublin. We currently have an enrolment of over 580 boys and girls and a staff of over 30.
This website aims to give you a taste of what we offer in our school, as well as providing up-to-date information for parents, pupils and the wider community.
Our key focus in Holy Trinity is the nurturing of every pupil’s holistic and academic development, in a safe and happy environment. Our dedicated and professional staff take pride in working to achieve the highest standards in education and holistic development. In addition to our teaching and learning programs in all key curriculum areas, pupil wellbeing is most important in our school.
Holy Trinity National School is under the patronage of the Catholic Archdiocese of Dublin and enjoys the support of the Sandyford Parish Pastoral Team when preparing pupils for sacraments. The School also receives great support and advice from the Education Secretariat of the Archdiocese.
We greatly value a close partnership between home and school and seek to foster and develop this relationship. We are dedicated to making the school days, of all our children, a positive and enriching experience.
We hope that you enjoy your visit to our website, and that you find the information you are looking for. Please feel free to contact the school directly with any queries you may have.
