Catherine's Philosoophy of Education

Catherine McAuley was born in Dublin in 1778 into a wealthy family. She later became famous for her work in helping the poor and the sick by providing them with food, homes, schools and hospitals. Some people were very poor in those days and there was little help for the sick and needy. Catherine wanted everyone to know the love and mercy of God and she did this by helping everyone especially those most in need.


Catherine set about building homes, schools and hospitals where the poor, the sick and orphans would be cared for. Many people began to follow the example of Catherine and to help out in the schools and hospitals.


She decided that she would like to give her life to God and become a nun. Later, in 1831 Catherine was appointed head of a new order which was to be known as the “Sisters of Mercy”.  “Mercy” schools, convents and hospitals spread throughout Ireland because of the good work which Catherine was doing. There are now many “Mercy” schools and hospitals in every corner of the world.

A Convent of Mercy was established in Cookstown in 1891 providing secondary, vocational and primary education to the community. Before then, there were no secondary schools in Cookstown and many children left school at the ages of twelve and thirteen to work in the local mills etc. Many older members of our community have fond memories of the commercial classes run by the Mercy Sisters.


Boys attended St Brigid’s Convent school until they were seven and then transferred to the “Boys’ School” on the Loy Street site. There was a National School on Loy Street since before 1861 and we still have records of the boys who attended the school at that time.

St Mary’s Boys’ P.S. was built in 1936 and later merged with St Brigid’s P.S  which was now located on the Convent Road site. The new school which opened in 1992 was called Holy Trinity Primary School. An extension was added in 1998 and a new Nursery Unit opened in 2001. The work begun by Catherine Mc Auley continues to this day…


In Holy Trinity P.S. today, we strive through our everyday teaching and learning to uphold Catherine's Values in:
  • caring ethos
  • concern for the disadvantaged
  • child centered
  • learning for life
  • high standards
  • home school links
  • faith based education
  • serving the community
  • praising and worshiping God through prayer and every day act

The original school desk, taken from the Convent of Mercy school is over 100 years old.

Many people will remember using an abacus just like this one.
