There are Sunday School classes for children in grades K-12. The classes consist of Bible lessons and activities.
Many classes have community service projects like visiting shut-ins.
The pastor holds periodic Confirmation classes for 7th-12th grade students. Taught over a period of 12 weeks, the classes introduce students to the beliefs of the United Methodist Church in order to prepare them for church membership. After completing the classes, the students participate in a confirmation ceremony during the regular Sunday worship hour. The Children's Choirs are a relatively new addition to Trinity's music program and perform for worship services and special events. Both choirs are conducted by Children's Choir Director Tracy Alexander.
