SIMS - Student/Teacher View
I was at the ASCL conference last week and found that a large number of SIMS users weren't aware of the Student Teacher view. This view is very powerful in that it shows all aspects of a student that teachers are interested in.
You have to elect to have this view as the default through Tools|Setup|Student Teacher view. If you aren't using it I would recommend taking a look. The traffic lights for attendance, achievement, behaviour and assessment are set up globally by the system manager.
