High School

Old St. Mary's School seeks to best support our students in continuing their Catholic education.
We know that choosing a high school to continue their education is an important and oftentimes an overwhelming process for students and their families. This web page is designed to help assist in the Catholic high school admissions process. Each of the school logos below is a direct link to that high school's admissions page.
In addition to the individual high school admissions pages, you can also find the Archdiocese of Chicago's Catholic High School Admissions Information Page. For your convenience you may search Catholic High Schools by distance and gender at the Archdiocese "Find a High School" link here.
For any questions, please contact Ms. April or Ms. Jenn Hoff, the high school transition team at hsguidance@osmschool.com
