Mary Institute and St. Louis Country Day School
MICDS (Mary Institute and Saint Louis Country Day School) is a secular, co-educational, independent school home to more than 1,250 students ranging from grades Junior Kindergarten through 12. Its 110-acre (45 ha) campus[2][3] is located in the St. Louis suburb of Ladue.
Each of the school's three divisions operate somewhat independently as a "school within a school". The Lower School, also referred to as The Ronald S. Beasley School, or "Beasley" for short, is for students in grades junior kindergarten through 4. The MICDS Middle School, grades 5 to 8, is in the former Mary Institute facilities. The Upper School on the former Country Day School campus serves grades 9 through 12.
