I extend to you a warm welcome to our website. You are invited to browse the various pages within which will hopefully give you a good sense of the opportunities and experiences on offer in our school and the outstanding rounded education provided by our experienced, committed and dedicated staff. Ardscoil na Tríonóide is a voluntary secondary school under the trusteeship of CEIST. We first opened in 2007 after an amalgamation of two previous fine schools Scoil Eoin and Scoil Mhuire. We combine the best traditions of both schools to create a rich and active learning environment with a strong focus on the holistic development of each student and on high academic standards in teaching and learning.
