How do I make a question mandatory?

You can require a respondent to answer a specific question before moving to the next section by ticking the Required checkbox on that question.

1. In the Assessment Builder, open the question (click Edit on the question card).
2. Tick the Required checkbox.
3. (Optional) Enter a Custom Validation Message to replace the default error text shown to the respondent if they try to proceed without answering.
4. Click Save.

If a respondent tries to move on without answering, the standard error message reads: "[Question Text] is required." For questions longer than 100 characters, the message is shortened to just the word Required. Use the Custom Validation Message field if you want a friendlier or more specific prompt.
