In August 1953, 104 students formed the first classes at the Holy Family School. With no specific school building, they met at the Saint Thomas Orphanage for the first year. The original school building was built in September, 1954. The student body almost doubled to 205 children in grades K-8 who studied with the Benedictine Sisters from Yankton, SD.

When the Cathedral was built in 1965, Holy Family School became Cathedral of the Risen Christ School. Since this time the school has increased in size twice by additional construction. Today's student body has doubled again to 350 students in grades PK through 8th.

Liturgy plays a central role for each student and staff members at Cathedral. Daily attendance at Mass, with students participating in preparation, reading, petitions, and offertory places the Mass in first priority. Students and staff also have monthly Confession, Exposition and Benediction services scheduled. Core subjects of religion, math, science, social studies, reading, and literature are taught on a daily basis, with new, updated materials always available.  Cathedral's mascot is the Eagle, and the building supports multiple clubs and organizations while also funding athletics for girls and boys, for the development of their mind, body and spirit as a holy child of God.

Cathedral school has initiated other programs to provide services to the community. A preschool program began in 1991 to provide classes for children from ages three through five. In 1992, the Extended Daycare Program was opened. This program provides before and after school care for students attending Cathedral.   Today the Cathedral website and social media is used to promote children's work and the school's story.
