MEHLVILLE, Mo.—The St. Simon the Apostle School in South County will close at the end of the school year, the archdiocese announced Thursday.

The school faces financial challenges due to declining enrollment, with only 70 students enrolled for the 2025-26 school year.

There are currently fewer than 30 students in first through fifth grades, with just three students in one grade.

"This ongoing trend means that continuing to provide quality education at St. Simon School would require financial support that would negatively impact the parish’s finances and impede other crucial ministries," Most Reverend Mitchell T. Rozanski, archbishop of St. Louis, said in a statement. "After consultation with archdiocesan leaders to explore possible cost-reducing options, we have determined that such changes would take away key services and resources from students and teachers and still require a growing and unsustainable parish subsidy."

The Archdiocese of St. Louis says the church will provide placement assistance to St. Simon School families and staff.
