The School Board serves as an advisory committee and meets once a month, except June and July. The meetings are open to all parents of children at St. Thomas School. To address the school board you must contact the president in writing seven days before the meeting and be approved for the agenda. The oral presentation of the matter is limited to two minutes unless this rule is suspended by majority vote of the school board present. This is in accordance with Article Six - Meetings of the School Board Constitutions. The main goal of the school board is to help establish school policies.

The school board members are: LaDonna Poehler (president), Gina May (vice-pres.), Delaine Ochs, Lisa Huston, Karen Buerster, Gary Buerster, Joyce Johnson, Apryl Stark (secretary) and Tony Zuber.

The school board meetings are scheduled for the first part of each month at 6:10 in the school library.
