If your survey takers need more time to complete the GTA survey, you can extend the End Date for your survey group.
All you have to do is:
1) Log in at https://learning.aperianglobal.com/portal
2) Navigate to the GTA survey platform (either via the link on your Welcome page or via a link in your Messages inbox)
3) If you see the My Teams page (because you have multiple team surveys), click on the name of the survey group you want to edit.
4) When you're on the Update Team page, edit the End Date value, then click the Save & Close button at the bottom of the page.
