How to remove a student account/user profile from a Chromebook:
- On the sign-in screen, click the profile that you want to remove.
- In the upper-right corner of the profile picture, click the downward arrow icon.
- Click Remove this user.
Removing a user profile deletes it from the Chromebook, but doesn't delete the Google Account or any data and settings synced with the profile. If you change your mind, you can add back a user you removed.
