Dioceses have successfully experimented with other schedules, such as, two years of weekly sessions. The program is conducted in two cycles. Each cycle includes three weekend sessions. New participants may enter the program at the start of a cycle.
Participants remain in the program for two cycles regardless of when they begin.
This is best done as a residential event. Plus expenses - travel, room, meals, phone, materials, etc. Trainers may work in teams. The diocese may have sent them through the required training or they may have gone on their own. CDI Trainers can arrange to send a training team into the diocese.
