School Saint Boniface previously had its own parish school, Saint Boniface School, which started operations in 1847. Classes were initially held in private residences before being held inside the church facility. It received a permanent school building in 1870. The school moved into the church in 1922, and a new school building opened in 1924. In 1987 it consolidated into Archbishop Hennessy Catholic School, which had two locations: grades K-3 in New Vienna, and preschool and 4-6 in Petersburg. It served as the joint parish school for Saint Boniface as well as Saints Peter and Paul Church in Petersburg. Enrollment was over 100 at that time. The school had a relationship with Beckman Catholic High School in Dyersville. In 2013 the school consolidated all grades into its Petersburg location. Its enrollment at that time was 60. Enrollments consistently decreased prior to 2017: by 2017 the school only had 45 students. Archbishop Hennessy closed in 2018. The remaining Catholic grade school in the "Spires of Faith" Catholic church network is St. Francis Xavier Catholic School in Dyersville.
