In Ranelagh in south Dublin, the school has a lay principal, Mr Patrick Potts, and about 420 students, with about 40 teachers.
Founded in 1950 after encouragement from the archbishop of Dublin, Dr John Charles McQuaid. According to Jesuit history he was concerned at the "number of well-to-do parents sending their children to England for secondary education." In 1974 a proposal was turned down by the Department of Education to turn the school into a comprehensive.

Crescent College
In Dooradoyle, Co Limerick, this co-educational comprehensive was founded in 1859, but entered the State system in 1971, following encouragement from its former pupil and minister for education, Donogh O'Malley.
The school is run on the basis of a split trust between the Jesuits and the Department of Education. The move to Dooradoyle from Crescent House was made because the old buildings were declared unsafe.
