This will vary from site to site and could depend upon:
- work-related interruptions,
- number and duration of interruptions, and
- the number of trainees.
Syscob recommends that each training session be no more than 4 hours in duration with at least one short break during the session — as that is about the extent of the concentration most persons can provide while retaining the information learned. This means that the training is usually spread over two to three days (depending on which version you have purchased).
