# Lock Screen

The Teacher can lock the screen(s) of one or more Students in the class. The message and the background image (if using) to be displayed when the screen is locked can be configured. See [Lock Screen](/faronics-insight/using-faronics-insight/the-insight-teacher-console/settings/lock-screen.md) for further information.

When the Teacher chooses to enable the *Focus* restrictions for *Lock Screen*, whatever *Lock Screen* settings that have been configured and chosen for the class will be applied to Student computers. If there are no settings created or selected for the current class, the default settings will be applied. 

For example, the Teacher has set the *Lock Screen* settings to display the message Eyes *to the Front of the Class* with an image background. When the Teacher selects to lock the screens of Students, the Student computers will display the preset message and designated background on their screens.

### How to Lock a Student's Screen

1. Select at least one Student.
2. Click *Focus.*
3. Click *Start* next to the *Lock Screen* option.

## 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://docs.faronics.com/faronics-insight/using-faronics-insight/the-insight-teacher-console/focus/lock-unlock-student-screen.md?ask=<question>&goal=<endgoal>
```

`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.
