The Catholic Parish of Raheny asked religious order the Poor Servants of the Mother of God to open a convent and schools in 1952, and the order, having agreed, bought Manor House in March 1952.

The Poor Servants of the Mother of God reduced their role in later decades, and created a Board of Management in 1989, on which their appointees held four out of eight seats, with the school principal attending as Board secretary but not voting.

[citation needed] In 2007, the school sold the most remote field of its sports grounds, and this has been developed with apartments.

[4] In 2018 the school and Fighting Words published a book of short stories by Transition Year students, Beyond Boundaries, with support from established author Sinead Moriarty and with Roddy Doyle joining the launch.

Several members are directly chosen by the Trust, others are nominated by parents and teachers, and the Principal is a non-voting attendee at Board meetings.

There is also a library, renewed in 2017 and opened by past pupil and author Alex Barclay.
