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.

This Sunday Academy faculty, staff, administration, and the Board of Trustees will welcome the ISACS (Independent Schools Association of the Central States) Visiting Team as part of our accreditation process. For the past three years, the Academy has been preparing for this visit, led by Steering Committee co-chairs Robynn Horner and Michael Taylor, along with Mary Reepmeyer and Tim Horner. Below, Mrs. Horner shares the process that has brought us to this point.

Over the past three years, the faculty, administration, staff and Board of Trustees at the Academy have been working to become fully accredited by the Independent Schools Association of the Central States (ISACS).

You may be wondering, “What is ISACS and why is it an important distinction for our school?” ISACS is a nationally recognized accrediting organization that evaluates Independent Schools through a comprehensive and rigorous review process. There are 240 ISACS accredited schools in the 13 central-states region, and we are proud to join the ranks of these prestigious schools.

ISACS accreditation supports our goal to provide an exceptional education for our students. It helps ensure our programs are academically rigorous, our environment is safe and supportive, and our faculty, staff, and leadership are aligned with our mission. It also confirms that our school meets established standards of excellence in academic programming, faculty and staff qualifications, governance, financial stewardship, and institutional stability.
