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


December 19, 2025

This week Fifth and Sixth Class students reflect on what Advent means to them and how they prepare for Christmas.

Advent means preparing my heart for Jesus to come in. I love getting ready by making Advent calendars, wrapping gifts, and giving presents because it makes me feel closer to Jesus. At the Academy, we even get time to make gifts for our families. This year, we’re creating calendars with ideas for small acts of kindness, like helping with dishes or wrapping presents.

Doing service at the Academy has always made me feel like I am really impacting some people that may not be able to afford what we might take for granted, like clothing and food on our dinner tables. It’s amazing that the Academy gives Middle Schoolers this opportunity. Also, for many years, our families and friends have come together to assemble baskets that we bring to Christmas Basket Mass to join those of Academy families. My family goes to Christmas Eve Mass in the Shrine, and it is my favorite mass of the year. It reminds me to open my heart fully.
