When viewing dashboards, there are 3 assessment ratings that can be shown:
Supervisor assessment ratings
You can switch dashboards to show either of these values by clicking the view preferences button at the top of the screen (by default Averaged ratings)
This will allow you to switch the view mode of the dashboards and reports.
*Note - some security groups may only be allowed to view one type of rating (Self-assessment only or Supervisor assessment only). In this case they will be defaulted to the view they are allowed to see and will not have an option to switch the view preferences
