It's best practice to disqualify respondents using Prequalification Questions whenever possible. Custom Terminate Logic is the fallback for when you need to disqualify respondents within PQs or the first three questions of a survey, based on specific demographic requirements or survey answers.

What Is Terminate Logic

Terminate Logic ends a survey for a respondent who doesn't meet certain criteria. A terminated respondent does not count toward your desired sample size—only respondents who complete the survey are counted.

Terminate Logic may be placed in PQs or within the first three questions of the main survey body—most commonly in single choice, multiple choice, and matrix questions.

In the example below, respondents who both purchased Brand A more than 7 months ago (from Q1) and plan to purchase it more than a year from now would be disqualified from the survey.

💡 Tip: To use Terminate Logic on DIY surveys, complete the Custom Quota Logic course in the Lighthouse Academy first.

Setting Up Terminate Logic

Terminate Logic must be written in questions that all relevant respondents will see.

⚠️ Note: Write Terminate Logic only into questions that don't contain hide or skip logic. If a respondent never sees the question the logic is written on, the disqualification can't fire.

Terminate Logic vs. Skip to Exit Logic

Terminate Logic and [skip to exit] both end a respondent's survey early, but they behave very differently—and mixing them up can throw off your completes count.

💡 Tip: If your goal is to exit a respondent without affecting your completes count, use [skip to exit] instead—see How to Use Skip to Exit Logic.
