What Mary Institute and Saint Louis Country Day School does
Mary Institute and Saint Louis Country Day School (MICDS) is a private, nonprofit, non-sectarian independent day school founded in 1859 and headquartered at 101 North Warson Road, St. Louis, Missouri. The school delivers JK-12 education across three sequential academic divisions: the Ronald S. Beasley Lower School (Junior Kindergarten through Grade 4), the Middle School (Grades 5-8), and the Upper School (Grades 9-12), serving families in the St. Louis region seeking a continuous private-school pathway from early childhood through college matriculation.
Beyond core academics, MICDS operates an extensive extracurricular and ancillary portfolio. Athletics includes Upper School and Middle School teams across multiple sports, with facilities such as Werner Stadium, the McDonnell Athletic Center, and an on-campus Fitness Center. The arts program leverages dedicated venues including the Messing Gallery, BAC Vincent Price Theater, Orthwein Theater, and Brauer Auditorium. The school also runs summer programming — Camp Pegasus, the Eliot Summer Academy, and the STL Summer Sports Camps — that uses campus capacity during the off-season. Supporting services include College Counseling and Matriculation, Global Learning initiatives, Community Service, After-School Programs, libraries (Messing Library and McCulloch Library), and a Winter Term intensive course offering.
The business model is tuition-funded with supplementary philanthropic support from an active development function. Revenue is not publicly disclosed, but operating revenues are complemented by structured giving programs (The MICDS Fund, One Day for MICDS, MICDS Madness, Matching Gifts, Planned Giving, Reunion Giving) and by capital campaigns such as the 2026 Beasley and Beyond Lower School Renovations drive, which raised $160,455 through a Board of Trustees challenge. The school uses Veracross for its admissions portal, student portal, and inquiry forms, embedding operations in a multi-school student information system ecosystem. Headcount is reported in the 101-250 range; leadership includes Head of School Jay Rainey along with division heads and an Assistant Head of School for Teaching and Learning, with an active Head of School succession underway.
