Within a decade of the formal establishment of the parish, the parishioners and their pastor deemed it of paramount importance to establish a school which the children of the parish could attend. In the school they would learn the basic skills needed for daily living and receive sound religious instruction. They would also be exposed to the Polish language, culture, and heritage. The children would be taught in Polish and English. Three Felician Sisters opened the first parish school in 1897 using two classrooms in the basement of the church. The Franciscan Sisters of St. Joseph have staffed the school since 1902. Since the middle of the twentieth century, lay teachers have been added to the staff as there has been a dearth of Sisters.
As the school grew, many changes were made. New school buildings were constructed. After the construction of the second church, the first church was converted into a school and parish hall. Within a few years more school space was needed. Section I of the brick school was constructed and opened in 1916. In 1925 the first church was demolished to provide space for Section II of the brick school. The enlarged brick school was opened in 1926. It had served as the parish school and center until 1973 when a devastating fire destroyed it. A new school which had arisen from the ashes was opened on January 5, 1976. The curriculum has been continually evaluated, upgraded, and expanded to provide an exemplary program of education for the children from Pre-School through Grade 8. The school was accredited by the New England Association of Colleges and Schools in 2000.
