When creating a test on TalentScore, by default it will not be shared. If you would like to share a test it is possible to do so. It would mean that any other division/team on your account will have access to it.
To see if any divisions/teams have shared a test with you, click on 'Tests' at the top and then 'Tests shared by other teams'.
You can clone the test and it will appear in the 'Your tests' tab. It will then be possible to edit the test as well.
