Sometimes, despite your best efforts as an administrator to encourage your survey group members to complete their surveys by your stated End Date, circumstances are going to prevent some of your invitees from completing the survey on time.
It's easy to extend the End Date of your survey group, whenever you like and as often as you like, to accomodate your survey takers.
If your survey group has expired, but you wish to extend it to allow more of your participants to access and complete the survey, all you have to do is:
1) Log in at https://learning.aperianglobal.com/portal and navigate to the IES dashboard
2) On the IES dashboard, click on the name of the Survey Group you want to extend
3) Change the End Date value to a new date in the future
4) Scroll to the bottom of the page and click Save and Continue
When you return to the IES dashboard, your survey group will be open and active again. You can then click the Email Reminder if you wish to notify people who didn't complete the survey in the original timeframe that they can go back and complete it now.
