The official opening was performed by Bishop Edward Ellis on Tuesday, 4 May 1965 followed by a reception by the Lord Mayor of Leicester, Alderman Kimberlin, OBE, one of the founding school governors.

Mr. Edward Brennan succeeded as Headmaster in 1966 and subsequent Heads have been Mr. David McLean in 1983, Mrs. Catherine Fields (Principal) 2002, Mr. Marius Carney 2007 and Mr. Mathew Calen 2022.

This building was dedicated and blessed by Bishop McGuiness on Thursday, 5 October 1978 assisted by Canon McReavy, Chair of Governors and Mr. Brennan the Headmaster.

In 2013, the school began a major rebuilding program which involved the construction of new classrooms and a library; a sports centre (including a professional astro turf hockey pitch); a Sixth Form block and St Cecilia Performing Arts Centre.

These are a bronze Crucifix erected at the entrance to the school by the Welsh artist, Helen Sinclair; an Icon of the Virgin Hodegetria by Aidan Hart; (card included) a cut slate plaque of the school motto "Ut omnes unum sint" by Lida Cordoza (Kindersley Cordoza Workshop, Cambridge); a choral setting of the school Prayer "Lord Jesus Christ make me a better person" by composer Simon Lole for the school's Schola Cantorum and a new two manual and pedal 16 rank pipe organ, built for the auditorium by Leicestershire Organ builder, Peter Collins.

The Chapel, which is dedicated to the Holy Family, contains two stained glass windows one of the St John the Evangelist and the other The Annunciation.

Tiles excavated by archaeologists from the floor of the abbey church were given to the school by Leicester University in 2015 and are displayed in the library.
