St. Petronille Parish School consists of Preschool 4 year old program, Kindergarten, the Lower school (grades 1-4) and the Middle school (grades 5-8). There is a strong emphasis on a rigorous but appropriate learning level for each and every child through all academic subjects: 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, also used to enrich the learning experience. The curriculum is tied to Common Core State Standards and Joliet Diocesan Standards, with an overall focus on God's truth, beauty and goodness.  We beleive that this faith foundation will allow students to truly understand how and why we are all on-going learners, which leads to personalizing each core subject.

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.  We work to help students experience a personal relationship with Jesus, while understanding gosple values and virtue based leadership. They come to learn in the larger framework of a deeper faith life, and further knowledge sacred tradition and eternal salvation.
