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.

We have been celebrating Catholic Schools Week with treats, activities, and some surprises. As this week draws to a close, we share some student responses to how the Academy supports them and helps them grow in their faith.

How does the Academy help you grow in your faith?

The Academy offers so many opportunities for me to grow in my faith. We attend Mass and we also take religion as a core class. My teacher teaches us about our religion and how to continue to grow in our faith. We also do service activities that help us to remember how many gifts God has given us.

The Academy helps me grow in my faith by having the five Goals which ensure you’re living through Jesus. These Goals help me have guidelines outside and inside the school making sure I follow Jesus.

— Class of 2027 student

We have a very loving community, and we also have great traditions. We have Mass every First Friday, and after Mass we do something called team building, which is when we go into assigned groups with the whole school and do fun activities. We also have the remains of a saint in the Shrine which is very special because St. Rose Philippine Duchesne was amazing in helping make our school the great place it is today.

— Class of 2026 student

I feel comfortable sharing my values and discussing my faith in class, as the classroom is a safe space for everyone no matter what. This is something that the Academy has told and assured over the last 10 years, and makes me feel open to share my opinion without fear of judgment.
