# Add participants from a screener to a usability test
If you’ve already found participants in a Dscout screener, you can add them to a usability test without having to screen them again. First, you’ll select this as your recruitment option when creating your study. Then, you’ll select the screener and the participants you want to add from it.
{% hint style="info" %}
You can only use one recruitment approach per study. So, if you’ve already set up your study to recruit from Dscout’s Scout Panel or to invite your own participants, you won’t be able to add participants from a screener.
{% endhint %}
{% stepper %}
{% step %}
When creating your study, select **Add from screeners** as the recruiting approach.
{% endstep %}
{% step %}
On the **Overview** tab of your mission, click **+ Add participants** in the left sidebar. A list of screeners in your project is displayed.
{% endstep %}
{% step %}
Select the screener you want to add participants from. The list of participants for that screener is displayed.
{% endstep %}
{% step %}
Use the checkboxes in the left sidebar to select the participants you want to add to your study. A list of available actions is displayed at the bottom of the page.
{% endstep %}
{% step %}
Click **Invite to mission**. A list of missions in your project is displayed.
{% endstep %}
{% step %}
Select the mission you want to add the participants to.
{% endstep %}
{% step %}
Click **Invite**.
{% hint style="info" %}
If your mission has already been launched, these participants will receive an email invitation immediately.
{% endhint %}
{% endstep %}
{% endstepper %}
{% hint style="info" %}
If you only want to add one participant from a screener to your study, you can also click the three-dot icon beside their name in the right sidebar. Then, select **Invite to mission** and select your mission from the list.
{% endhint %}
Now, your selected participants are listed under **Participants** on the **Overview** tab of your mission. If you want to add participants from multiple screeners, repeat the above steps for each beginning with step two. Once you launch your mission, they will automatically receive an email inviting them to participate.
If you want to remove a participant, click the **Remove from mission (trash)** icon in the top right corner of their tile. However, participants can’t be removed from a mission once it’s launched.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://help.dscout.com/usability-tests/what-are-usability-tests-in-dscout/add-participants-from-a-screener-to-a-usability-test.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
