It is sometimes desirable and even necessary to disciple people in groups. Whether you meet informally in a home, or in the organized surroundings of a Church, you can train many people using the five Discipleship Study Books.
In the Church setting, available classrooms and teachers will allow an ongoing training course with simultaneous classes on every level. After completing the Discipleship Study Five, students can continue on with Book Studies, Character Studies or Topical Studies (ie. Practical or Systematic Theology, Apologetics, Ministry Training, etc.)
Students should be encouraged to retake any level as a review. Repetition enhances Learning!
