News & Events

The Senior School Leadership team received their badges from the Principal, Mr Martin this morning. 

Following interview, Ronan McCluskey was selected as Head Boy for 2018-19, with Finn McCann, Eamonn McCullough and Ciaran McCaffrey as Deputy Head Boys, with specific responsibilities for KS3, KS4 and Post-16 respectively. 

Ten other Year 14 students were selected to be Senior Prefects with various roles throughout the School.  It was obvious that the students had put a tremendous amount of effort into preparation for the interview, as the calibre of responses was extremely high.  We would like to thank the students for their commitment and wish them well as they take up their new roles.

We are delighted to invite you to our now annual fundraising QUIZ at the school on Friday 28th September.

Bring your own 'refreshments' and relax while helping the PTA provide an outdoor secure lockup for our recently acquired defibrillator.

It is with great sadness that we announce the passing of an esteemed friend and colleague John Donnelly.
John was a much loved member of the St Mary's staff from 1972 - 2016 and one of the true characters who always brought a smile no matter where he went.
Our condolences and prayers to his family and friends.

Is le croí mór trom a fhógraím go bhfuil dlúth-chara dár gcuid, John Donnelly imithe bealach na Naomh.
Ba mhór an cion a bhí againn ar JD agus is iomaí duine, idir scolairí, baill foirne agus teaghlaigh Scoil Mhuire a ndeachaigh sé i bhfeidhm orthu.
I measc Naoimh na nGael go raibh a anam caoin.


This is an invitation to all of our Year 14 students who left in June 2018 and their parents, to the senior prize giving on Wednesday 5th September at 7.00 pm

We would encourage all of our leavers and their families to join us for this celebration of the successes of class of 2018 before departing for university or the world of work.


Our Year 8 students were welcomed to St Mary's and began the day with a smile.
