St. Petronille Parish School consists of Kindergarten, the Lower school (grades 1-4) and the Middle school (grades 5-8). There is a strong emphasis on basic academics: religion, reading, language arts, mathematics, science, foreign language and social studies. The curriculum is enhanced with enrichment in art, music, and physical education. Technology is integrated into all areas of the curriculum. The curriculum is tied to Common Core State Standards and Joliet Diocesan Standards.

Our Catholic faith is interwoven throughout the entire fabric of the school and its programs. Students plan and participate in class liturgies, all school Masses, and daily prayer. As part of the larger faith community, students take part in parish as well as classroom sacramental preparation. Altar servers add a spiritual service to the parish.
