At We_They we offer a wide range of subjects, academic and practical, in a non-denominational setting. We foster the moral development of students through a school ethos based on respect for the dignity of each inpidual. 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.

In addition to providing second level education to students over a wide catchment area, St Tiernan's runs very successful Post Leaving Certificate Courses and has a wide range of courses available to the public in our Adult Education Department. Local sports clubs and organisations avail of our facilities also, which makes St Tiernan's truly  "A school for the community
