Internal exclusions can be set up in Students> Behaviour> Setup > Internal Exclusion Types.
This page allows you to define the different types of internal exclusion you will be setting up.
Click +Add to create new Internal Exclusion types.
After creating an internal exclusion e.g Periods 1 and 2 you next need to add timetable slots to that internal exclusion.
After creating the Internal Exclusion it will take you automatically to the Timetable setup or you can come back to this later. (If you choose to do this later just highlight the Internal exclusion that needs to be timetabled e.g Periods 1 and 2 and click on this exclusion type. This will take you to the Timetable Setup overview.)
This can be done by clicking +Add at the top of the Timetable table.
This will allow you the choice of creating a one-off or a regularly occurring internal exclusion.
When the internal exclusion has been successfully timetabled, you can start adding students and additional staff to the sessions.
