Why the Academy?

The Academy of the Sacred Heart is an independent Catholic school in St. Charles, Missouri open to 3-year-old through 8th grade children of all faiths. Our program offers students the opportunity to learn and grow in a safe and happy environment, with a focus on building strong academic skills while fostering independent learning and communication. Curriculum highlights include: two Science labs, a Makerspace, 1:1 computing, French and Spanish, daily Physical Education, and recognized art, music and athletic programs.

Founded in 1818 by St. Philippine Duchesne, the Academy was the first of many Sacred Heart schools established in the United States. Our mission is to educate and inspire the heart and mind of each child to become a courageous and confident leader who knows and loves God, and who reveals that love by serving others. Our graduates are young men and women well prepared for the challenges of high school, college, and beyond.

From the Heart


January 8, 2026

As we begin the new year, we look to the five Goals of Sacred Heart education — the essence of our principles and values, shared by the 25 Network of Sacred Heart Schools in the U.S. and Canada. Both timeless and timely, these Goals and their supporting criteria express what is at the heart of Sacred Heart education.

This month, we will focus on Goal 1: a personal and active faith in God. Amaya Firestone, Marketing and Communications Assistant and Admissions Coordinator, shares some exciting news in the Archdiocese.

The Academy of the Sacred Heart and the Archdiocese of Saint Louis, under the leadership of St. Rose Philippine Duchesne and Bishop DuBourg, have a deep shared history of missionary zeal, perseverance, and frontier grit. In 1818, the same year of our foundation, Bishop DuBourg chose St. Louis as the episcopal seat of what would become the archdiocese of the western frontier. He shared Philippine’s incredible vision for the region, which at the time was a scarce and poor land. How far we have come from then to now: “The Rome of the West.”
