Trinity United Church School currently has an enrollment of 50+ children. The Church Nursery, located on the main floor, is a bright, newly decorated space with many toys and games for children up to three years. Childcare is provided every week, from fifteen minutes before the service begins. Volunteer staff consists of a minimum of one adult and one teenage assistant. More volunteers are available on busy mornings.

Graded classes for ages 3 & 4, senior kindergarten and grade one, grades two, three and four, grades five and six and grades seven and eight are located on the second floor and in the church parlour. The curriculum is Seasons of the Spirit, an ecumenical, lectionary-based program which integrates worship, Christian Education and Outreach. Each class has three teachers, who are free to design a teaching schedule which meets their individual needs. We also have a church school co-ordinator who helps with supplies and organization for special events.

We try to integrate church school learning with the life of the congregation as much as possible. The children take turns bringing the church school donations as part of the offering of the congregation each week. Children serve as lay readers and offer prayers. The Church School plays a major role in our early Christmas Eve service each year.

We plan several open sessions each year where the church school works on a project together. During our Christmas Craft Day in early December, we make Christmas decorations for shut-ins and those in hospital, a twenty year tradition at Trinity. For several years, we have had a field trip to the grocery store on World Food Day, to buy contributions to the Food Bank. On Thinking Day in February, we host the children of the 6th Trinity Beavers, Cubs and Scouts for a program which is often on a Lenten theme. Other Open Sessions are held on Long Weekends, during March Break and on major holidays when attendance at church may be uncertain.

Our goals for the church school are "to plan a comprehensive Church School program, in keeping with the values of the United Church of Canada, which enables multiple intelligence learning, creativity, the development of opportunities for friendship and a close connection with the worship life of this congregation".
