Junior youth groups meet once a week, though sometimes more, typically over a three year period and study materials that have been specifically developed for ages between eleven and fifteen. Studying occupies only a portion of the time the junior youth spend together. During the rest of the time, groups consult on and plan service projects, participate in sports, and engage in cultural activities, such as drama and crafts, suited to their immediate surroundings. In addition to these weekly meetings, groups attend special events and undertake acts of service to the community.
