What if a student using an iPad is told to disable Guided Access mode?

If a student sees an error message telling them to disable Guided Access, it’s because Apple Classroom or another application is preventing Bluebook from working properly. Do the following:

Perform a hard reset of the device. To learn how, refer to What if a student’s iPad freezes while it’s locked?
Close other applications.
Go to Settings > Accessibility > Guided Access.
If Guided Access mode is enabled, turn it off. Students using school-managed iPads might need school technology staff to do this for them.
If these steps don’t work, the student can use a backup device. If the start code wasn’t entered, they can simply switch devices. If the start code was entered, and the test hasn’t ended, follow the instructions in your Technical Troubleshooting Guide and use the device swap feature.
