Discipleship Training meets Sunday evenings before evening worship. There are classes for each age group: nursery, preschool, children, youth and adults.
Discipleship Training differs from Sunday School in its focus. Sunday School leans toward Bible study and evangelism; Discipleship Training serves as the training unit of the church. Discipleship Training’s tasks include training church members to perform the functions of the church; training church leaders; providing orientation for new church members; teaching Christian theology, Christian ethics, Christian history, and church polity and organization; and providing and interpreting information regarding the work of the church and denomination.
Discipleship Training has undergone several name changes. When it was started in the 1930s at Oak Grove it was known as Baptist Young People's Union (BYPU). Since then it has also been called Baptist Training Union (BTU), Training Union and Church Training.
