Hey @Aaron, welcome to the community!
NOCODE just means that the participant completed the study manually and not via the completion code you provided.
This usually occurs for one of two reasons:
It could be a technical problem with your redirect URL: The participant reached the end of your survey, but were not redirected back to Prolific via the completion URL for some technical reason. Therefore, they had no way to access the completion code and had to submit without one, or instead submitted the wrong code.
- These cases should be approved as normal if there is no issue with the submission; you should check your survey data to ensure that they fully participated in your study, and you can also use their completion time to gauge the likelihood that they did reach the end of your survey.
The participant decided to leave your study early, or could not proceed because of some technical issue. Instead of returning their submission, they have submitted without a completion code or with the wrong completion code by mistake, and appear in your ‘awaiting review’ list. If the data they submitted is incomplete, then it is likely this.
Is there one that seems more likely?
