We're using
Moderation date is basically a 'closure' date, after work has been submitted, marked and results released to learners.
Each module will have a different date and will be spread out over weeks.
We have set up a course with different topics/modules and each topic/module is a different discipline but they are all required for the qualification.
Currently we are not really utilising all the date models within individual activities or for the programme as sometimes flexibility is required within a timetable ie. the timetable has set dates but at the time, depending on client requirements, dates may be changed for submissions/closure etc.
