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

Admissions decisions will be mailed in early March. 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 an OSM Parishioner you have to be registered with the parish and do 24 hours of service at the church. In lieu of doing 24 hours of service families pay a fee. 

  • 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.

Students entering kindergarten must be five on or before September 1. Students starting 1st grade must be six on or before September 1 etc.
