My student created a teacher account by mistake.

While it's not possible to turn a teacher account into a student account, if you have a student who accidentally created a teacher account, tell them to go to and then sign up as a student.

Edpuzzle allows you to have a teacher account and a student account with the same username/email, so this won't affect their ability to create a student account.

If a student wants to delete their teacher account, they can do so from the profile page of the teacher account by going to the "Account" tab in their profile and clicking "Delete" at the bottom of the page. Log in and click here to go to your profile settings:
