Application and Enrollment Process


If you are interested in applying, applications can be completed by clicking here. Applications for new families must be submitted by January 31, 2020. In addition to the application, we also require a $50 application fee. Only completed applications, with application fee will be reviewed.


Parent Interview / Student Observation

You and your child will be invited to the school for an interview in February. We would like to get to know you, and your child, a bit better by inviting you in for a brief one on one visit. While your child is engaging with students and teachers, you will be meeting with the principal and pastor.

Admission Decision

Following an interview, families will be notified of acceptance on a rolling basis. Once a child has been accepted, a non-refundable registration fee of $1,500.00 must be submitted within two weeks of acceptance to confirm the child’s placement.


Admission Priorities

Admissions priority will be given in the following order:


  • Siblings of current students and graduates of OSM 


  • OSM Parishioners

       To be considered a parishioner families must be registered with the church. 

  • Parishioners of other parishes

       In order to be recognized as a Parishioner of another parish you need a signed letter from your pastor. The         letter should state the length of your membership and the service you offer your parish. 


  • Community

       After the aforementioned categories, acceptance to OSM is open to the community at large.


Catholic Values

Because Old St. Mary’s School is a Catholic school, children will be exposed to the values, customs, rituals, and teachings of the Catholic faith in the tradition of the Second Vatican Council. Children who attend Old St. Mary’s school, even though they may not be of the Catholic faith, will be expected to join in these formative activities. Parents are expected to support the growth and welfare of the school. By forging a partnership, the parish and the parents will be furthering not only the individual growth of their children but preparing them to live out the Gospel mission.


Age Requirements

Any child entering school must be in compliance with the requirements of the State of Illinois regarding age of admission. Preschool students must be three or four years old on or before September 1. Students entering kindergarten must be five on or before September 1. Students starting 1st grade must be six on or before September 1 etc.
