You can add a custom feedback message to a Diagnostic Assessment (either a Stand-alone Assessment or as part of a Pathway) which will be displayed to Users in the feedback screen.
Locate the Pathway that contains the Diagnostic Assessment (or the Stand-alone Assessment) in Content Manager and click on its title to be taken to the Administration area.
Navigate to the Details tab and scroll down to the Feedback upon completion section.
In the End of Assessment Message box, write your custom feedback message. Note: this is generic to the outcome of the Assessment, and cannot be customised for specific learning outcomes.
The message will appear to the User as below in the feedback screen, after they have completed the Diagnostic Assessment.
