Testable Minds FAQ

How do I post a study?

Section titled “How do I post a study?”

Go to your experiment’s Minds tab, click New Study, fill in the study form, and click Submit for Review. Testable staff review submissions during UK business hours (typically within a few hours).

Section titled “Do I need a completion code or completion link?”

Only if you are running an external study (the experiment is hosted outside of Testable). In that case, provide either:

  • A completion code from your external platform, which Testable Minds displays to participants on finishing.
  • A redirect URL that sends participants back to Testable after they complete the external task.

For experiments hosted on Testable, no extra configuration is needed; completion is handled automatically.

How much does it cost?
