Mary Institute and Saint Louis Country Day School (MICDS)

MICDS offers a dynamic learning environment for intellectually curious and ambitious students from junior kindergarten (age 4) through the 12th grade. MICDS is one school, comprised of three divisions, each addressing the academic and social needs of students at every point in their development.


MICDS’ unmatched education in math, science and the humanities provides strong academic skills and encourages a lifelong love of learning. The School’s mission is to help students lead a life of discovery by uncovering their passions and preparing them for a life of purpose and service as compassionate, engaged citizens of a global community.

MICDS teachers are skilled educators and experts in their field who serve as mentors, instructors, and coaches. The curriculum provides students with deep conceptual understanding across disciplines and grade levels. Students enjoy small class sizes that promote vibrant intellectual exchange and a strong spirit of community.

Student learning is optimized by unparalleled facilities, which reflect the school’s ongoing investment in its students’ futures. The one-to-one laptop/tablet program facilitates an engaging curriculum and individualized instruction. The school’s state-of-the-art STEM facility is the most advanced secondary education building in the region and provides access to laboratories for research, plant sciences, and robotics. New athletic facilities, the Steward Family Aquatic Center and O’Hara Field, enhance a strong athletic program and reflect the school’s commitment to excellence in all endeavors.

At MICDS, “Changing Lives, Changing the World” is not a catchphrase, but a powerful testament to the remarkable potential the school has to transform the lives of those in its care.
