Some departments teach more than one year-group per class, eg Higher Physics contains S5 and S6 pupils. The multi-year department class component allows you to combine pupils from different year groups into one class.

Creating a class like this has a number of advantages.  Pupil registration is straightforward, since all pupils appear in the one class.  Preparing reports, tracking & monitoring are also more straightforward since staff have ready access from their class list, from a single screen.
