Why the Academy?

Exceptional Academics

Beyond STEM, international language, art, music and daily PE, Academy students are recognized in high school for their strong foundation in literature and writing. With high school-level Algebra 1, Eighth Class students are well prepared for honors math. Graduates consistently place into advanced level classes and are known as leaders in their secondary schools. Graduates are admitted to their top choice high schools.

Our Community

Building a community that is warm, welcoming, and inclusive is integral to Sacred Heart education. Students learn to celebrate the accomplishments of each other and support one another through challenges. Geographically, the Academy draws students from 24 zip codes from across the St. Louis/St. Charles metropolitan area.

Favorite School Activity

Student-Teacher Ratio

An 8:1 student-to-teacher ratio and an average class size of 14 students ensures that each child receives individualized attention and is known deeply. Our small-by-design class model supports differentiated instruction and fosters relationships which encourage personal growth. 

Confident Communicators

From their youngest years, students have the opportunity to practice and grow in their communication skills with peers and adults. In addition, students regularly present to their classes and to the wider school community.

Faith

A Catholic school for children of all faiths, the Academy instills a personal and active faith in God. Through an education infused with faith, students grow in their relationship to God. Faith is expressed through prayer, liturgies, religion and theology classes and in espacio, a daily practice that allows all members of the community to still themselves, reflect and pray.

Service Learning

Each year, students are commissioned to be service learners: the hands and feet of God in our community. An Academy education awakens students to the needs of others and a desire to make a difference in the world. As part of a robust service learning program, Middle School students spend one morning a month at area agencies, organizations and assisted living residences and look forward to building relationships.

Traditions

Customs, traditions, and feast days are a major part of  life at the Academy of the Sacred Heart.

  • Monthly First Friday Liturgies bring everyone together to celebrate and express our love of Jesus and our love for each other.
  • Surprise Congé play days come when least expected! On this day the Eighth Class have an opportunity to exercise skills of planning and organizing fun activities for the younger ones.
  • May Crowning keeps the tradition of honoring Mary, the Mother of God, by having the children frequently say the Rosary before the start of school days in May. The culmination of May’s dedication to our Blessed Mother is the formal May Crowning ceremony.

Alumni Connections

“My Academy education guides me every day as a teacher, a person, and a citizen.”

Academy alumni give back to their school and in their communities. Alumni have pursued successful careers in a wide range of professions, including medicine, law, business, politics, engineering and the arts. There are filmmakers, published authors, social workers and some who have entered the religious life. Many have followed the pathway to education, and dozens have returned over the years to teach at their alma mater. No matter their career path, these men and women remain loyal and supportive to their alma mater and return when they can to the place they call home.

Once they graduate, Academy alums become members of the Associated Alumnae and Alumni of the Sacred Heart (AASH) with unlimited connections for career networking, travel and friendships.

STEM

At the Academy, students receive more than 300 total hours of dedicated STEM instruction. From State Robotics competitions to personalized, engaging math instruction, Academy students graduate with knowledge in coding, engineering, life and physical sciences, and math skills so that they are well-prepared for high school and beyond.

Welcome from the Admissions Office

Envision a school where students walk through the vibrant hallways feeling confident, cared for, and respected: that’s the Academy of the Sacred Heart in Saint Charles, Missouri, founded in 1818 by Saint Rose Philippine Duchesne. In our school students truly develop a love of learning while developing wise freedom. Beyond the school walls, students graduate as community builders who care for others.

We invite you to tour our school and see our exemplary educators in action. They are engaged with our young learners, and they are tailoring learning to meet their individual needs. As parents, this is what you hope for your children – to be seen and to meet their God-given potential, and that’s exactly what our teachers work toward with skill and sincerity.

This year, we have a variety of admissions events to showcase our Sacred Heart education. Please register for our admissions events and schedule a tour to see and experience a school with HEART.

Best regards,
