Holy Spirit GNS was established in 1968 under the patronage of the Catholic Archbishop of Dublin, Dr Charles McQuaid in the parish of Sillogue.

The teachers originally taught in St. Pappin's school, which has long since gone. St Pappin's School stood on the site of the present nursing home in Coultry.

While waiting for the new school to be built, pre-fabs were erected where the children's playground now stands to the rear of the present school. Mrs Sorcha Sheehy was appointed the first principal of the school and Nora Neylon was the Deputy Principal. As the parish church was not yet built, the school hall served as the church until 1979. The school then had 16 classrooms and a cookery room.

It quickly expanded and in 1973 an additional six classrooms were added, with an All Purpose Room. Pupils numbers swelled to 1,052 pupils and 30 teachers including the principal. In 1976, the first learning support teacher (SET) was appointed and in 1977, a special class was established(the special class was disbanded in September 2011).

In 1993, approval was granted to refurbish the main school building (3 million) but not the Administration block.

The Administration block and school hall were refurbished in 2004-2005 with a glass walkway on the first floor, linking the two parts of the school.

Today, Holy Spirit GNS has 23 teachers, including the principal, 4 SNA's and ancillary staff and services.

Through all the years of change and development in Holy Spirit GNS, we are happy and proud to have kept the friendly, caring, child-centered community spirit alive in our school. Holy Spirit GNS school is thriving and we are excited to be educating the young people of this great community for life in the 21st century.
