The original St. Andrew’s School founded in 1827, was built in the centre of the village opposite St. Andrew’s Church and incorporated the Schoolhouse, residence of the School Principal. Mr. Sam Adamson, Principal, and his wife Zephra (Effie) lived there for over 20 years.

The school has grown in spurts over the years. In the years preceding the Great Famine of 1845 numbers may have been greater, but if not, St. Andrew’s remained a one teacher school for 127 years. The teacher acted as Principal and class teacher to all pupils from Infants to Sixth and sometimes Seventh Class. Records in the school date from only 1940 when there were 18 pupils on roll and Mrs. Ireland was Principal. She retired in January 1954, Mr. Sam Anderson was appointed Principal and his wife Effie was Assistant Teacher. There were 40 pupils on roll. It remained a two-teacher school until 1971 when a third teacher was appointed.

In 1972 the school moved to a new location set at the top of Chapel Hill on the edge of Lucan village. On 3rd November 1972 the new school site was officially opened by Mr. Padraig Faulkner Minister for Education and blessed by the Archbishop of Dublin Dr. Alan Buchanan.

We moved to our present new school located in St. Edmundsbury in 2015 and the fabulous new state of the art school was officially opened on the 29th April 2016 and blessed by Archbishop Dr. Michael Jackson.
