Application Process

Thank you for your interest in the School of St. Mary. We can’t wait to welcome you to the Crusader Family!
Applicants are welcome at any grade level at any time. Admissions are determined both by capacity availability and a comprehensive review of the student’s academic standing (for kindergarten - 8th-grade applications). Applicants may also be assessed by the SOSM student services team to determine their academic fit within our program.
We are looking for…
  • Children who meet social and academic expectations as determined by an admissions committee. 
  • Parents with a strong commitment to the mission and culture of our school and who want to make a long-term commitment.
NOTE: While submitting an application by December 1 is recommended for new SOSM families, we welcome applications throughout the year. Please contact the Director of Admissions, Mandy Castle, with any questions. 


How to Apply

To apply for admission to the School of St. Mary, please complete the following steps:



Step 1: Complete the online application






Step 2: Schedule a visit 

Schedule a meeting to look at the school and meet the principal. We offer both virtual and in-person tours. 

Incoming students in Kindergarten through 3rd grade will also need to attend an assessment day in June.


Step 3: Submit Grades

You will need to provide a copy of each student's most recent report card and test scores




Application Consideration

The School of St. Mary will consider the following factors in determining priority for admission:
  1. Children with a sibling currently enrolled at SOSM.
  2. Families who have been active, registered parishioners of the Church of St. Mary.
  3. Families who are committed to continuing their child's education at SOSM through 8th grade.

Transfer Students

Based on capacity availability, we accept transfer students at any time from other Catholic or public schools. Applicants must be in good academic, disciplinary, and financial standing in their current school for their admission to be considered. Student consideration requires completing the inquiry form, including submission of school transcripts, standardized test scores, and any IEP or 504 plans. Should space be available in the requested class, the student will be invited for a shadow day and formal assessment. In-person or virtual tours are available at any time. Request a tour here

Probationary Period

All new and transfer students to the School of St. Mary will be admitted on academic and disciplinary probation for their first year of attendance. 

Admission of any child depends on the agreement that parents or legal guardians and the child agree to abide by the policies, rules, and regulations of the Archdiocese of Chicago and the School of St. Mary. The school operates under the guidelines of the Catholic Bishop of Chicago, a Corporation Sole, in the Archdiocese of Chicago, and admits students of any race, color, sex, religion, nationality, and ethnic origin to all the rights, privileges, programs, and activities made available to students at the school. It does not discriminate on the basis of race, color, sex, nationality, or ancestry in administrating educational policies and other school-administered programs.
