ALL ABOUT US....
St. Mary's National School
St. Mary's N.S. is a rural co-educational Catholic primary school nestled in the heart of the beautiful village of Threemilehouse. We are located at the top of the hill opposite St. Mary's Church. We provide primary education for pupils from 4-12 years of age – Junior Infants to Sixth Class. St. Mary’s National School also provides three special classes for pupils with Autism Spectrum Disorder  aged 3-12 years – Cairde 1, 2 and 3. 

Characteristic Spirit & School Ethos
St. Mary’s National School is a Catholic primary school where we aim to promote the full and harmonious development of all aspects of the pupil – intellectual, physical, cultural, moral and spiritual - including a living relationship with God and with other people. St. Mary’s National School wishes to create a nurturing co-educational environment. Students are encouraged to develop their full potential in every aspect of their lives - academic, social, creative, spiritual, moral and cultural. We are an all-inclusive school where everyone belongs, where diversity is celebrated while developing individual self-respect and respect for others. St. Mary's N.S. is a school where successes are acknowledged and where mistakes are seen as learning opportunities. We endeavour to create a happy, caring, fun and hands on learning environment. The school promotes the philosophy of life inspired by belief in God and in the life, death and resurrection of Jesus Christ. Together with the school community we model a living Christian example which nurtures the faith of Catholic pupils in a manner that is welcoming to and inclusive of pupils committed to other religious traditions.
