You can reopen a closed study, even weeks after it closed. Credits attached to the study remain available.
Reopen a study on the older bookings layout
Open the study you want to reopen.
Click the Settings wheel.
Scroll to the bottom and select Reopen Project.
Add new session times in the Calendar straight away. A study closes automatically once all its session times have passed, so if you reopen without adding future times it can close again.
For an online task or survey, extend the completion date instead, or increase your quota to collect more responses.
Can't find a reopen option?
Studies in the current studies experience don't have a Settings page. If you can't see a way to reopen your study, message us on live chat with the study title and we'll reopen it for you.
Why did my study close in the first place?
Studies auto-close once every session time in the calendar has passed. Nobody on your team needs to have clicked anything. See How to close a study for how closing works.
Will existing participants see my new times?
Existing applicants aren't notified when you add new times. The fastest way to fill new slots is to send more invites than you need. People who are free will accept, people who aren't will decline, and anyone who accepts after a slot fills is waitlisted as a backup. More on this in Can participants see the new times I've added?
