Exam mode on student tablets: how to lock devices for assessments

By the SkieOS team · Updated 11 November 2026 · 4 min read

In short

Exam mode temporarily restricts devices to the assessment app, or a very short list, for a set time. Applied to a whole class in one step and reversed automatically afterwards, it keeps assessments clean without manual checking.

What exam mode should do

  • Open only the assessment app, or a short list
  • Close the browser and messaging
  • Apply to a whole class at once
  • End automatically at a set time
  • Report any attempt to leave

Setting it up

Create or choose the class group, set the assessment window and the approved apps. At the start time the devices switch; at the end they return to their normal rules.

On the day

The invigilator can see which devices are ready and which have reported a problem, down to the exact device. See real-time breach alerts.

After the assessment

Normal rules resume automatically so no one has to remember to switch them back.

Frequently asked questions

Can we apply exam mode to a whole class?

Yes. The change applies to every device in the group at once.

What if a device is offline?

The device keeps its last applied rules, and a silent device is flagged so it can be checked.

Can calls still work?

That is a policy choice, and can be allowed or blocked for the assessment.
