The school was founded in 1971, first as a Pre-University Centre at 144-116 St Stephen's Green, Dublin 2, offering repeat Leaving Certs for students. In 1972, classes were expanded. Later, in 1975, the school moved to Rockbrook House and surrounding forty acres buying them from John Brown, who was retiring as Chief Brewer with Guinness and moving back to England. The price paid was £75,000 Irish pounds. In the summer of 1980,additional classes were built, that is, five class rooms and a number of small mentoring rooms at a cost of £44,000 Irish pounds. In 2006-2008, Rockbrook took on the biggest step in its history, building a brandnew school building, car park, sports pavilion, and two new soccer pitches costing €5 million.
Schools ethos
The school was founded by a group of parents who wanted to combine academic excellence, personal attention to each student and sound moral development, along with a close working relationship between teachers and parents. Rockbrook's education is grounded on a Christian understanding of the world and of the human person. Drawing on Catholic educational principles and social teaching the school emphasises the importance of character development to its students. The school welcomes and respects students of other beliefs and accommodates these insofar as is practical. The school fosters a genuine and profound respect for others, regardless of talents, race, colour, creed or social standing. People are to be valued as persons, for who they are, not for what they are. Within the school this respect is fostered in an atmosphere of trust, openness and sincerity, and these qualities should characterise all aspects of school life and interactions between pupils, parents, teachers and management. Students in particular are encouraged to value their freedom and to use it well, taking responsibility for their own actions. The founding parents, notably Lord Kane, were inspired by St. Josemaría Escrivá, the founder of Opus Dei, a personal prelature of the Catholic Church. St Josemaria’s teaching about the value of one’s ordinary work as a stepping stone to God impacts on the school’s approach to encouraging hard work, excellence and a spirit of service within the school community. At the schools request the Prelature of Opus Dei make a priest of the Prelature available for the sacramental and pastoral needs of the school community. He has no role in the management of the school.
