Welcome to the Catholic University School

Catholic University School (C.U.S.) is a private, Catholic secondary school for boys in Dublin, Ireland. Under the Trusteeship of the Marist Fathers, CUS is located in the heart of Dublin, on Lower Leeson Street. The Marist Order was founded in 1836 and almost immediately the Marists set up schools which emphasised excellence in learning and provided a context which would develop a pupil’s sense of values in accordance with the Gospel. We believe passionately in the value of the education that we provide to the pupils who attend Catholic University School.

Where Tradition Meets Innovation

From the moment we attended the open day, we knew CUS was the right fit for our son. The school’s rich history and tradition, combined with modern teaching methodologies, create a unique learning environment. Our son has flourished here, developing both academically and personally, and we couldn’t be happier with our choice.

A Transformational Transition Year Experience

The Transition Year program at CUS exceeded our expectations. Our son had the opportunity to engage in various projects, work experience, and community service, which broadened his horizons and enhanced his maturity. It’s evident that the school places a strong emphasis on preparing students for real-world challenges.

Balanced, Supportive, and Inspirational

CUS has been instrumental in shaping my son’s teenage years. The school’s balanced approach to education, blending rigorous academics with sports and arts, has enabled him to become a well-rounded individual. The teachers are approachable and genuinely care about each student’s well-being and success.

An Exceptional Start to Secondary School

Transitioning from primary to secondary school can be daunting, but CUS made it seamless for our son. The welcoming environment, coupled with a range of extracurricular activities, has allowed him to settle in quickly and explore new interests. We’re particularly impressed with the school’s emphasis on both academic and personal growth.

A School That Truly Cares About Every Student

Enrolling my son at CUS has been one of the best decisions we’ve made. The school’s commitment to academic excellence is evident, and the small class sizes ensure personalized attention. Beyond academics, the emphasis on character development and values aligns perfectly with our family’s principles.

Preparing Our Son for Life Beyond School

As my son prepares for his Leaving Certificate, I can confidently say that CUS has provided him with a robust foundation. The dedicated teaching staff have not only prepared him academically but have also instilled a strong sense of responsibility and independence. The school’s focus on holistic education is truly commendable.
