Participant freshness rules

Researchers can now customize past participation rules on a per-project basis. Set a participation exclusion window from 0 to 365 days, or exclude all repeat participants if your study requires a completely fresh audience.

This option gives you more control over who qualifies for your research. Keep stricter rules for exploratory studies, or reopen your pool for niche audiences and hard-to-recruit professionals where repeat participation may be appropriate.

What's new

• Set a custom past participation exclusion window for each project.
• Choose any window between 0 and 365 days, or exclude all repeat participants.
• Quickly see whether an applicant is a past participant and meets your project's freshness rules via updated alerts.

As part of this update, the default exclusion window for new projects is now 90 days.
