Warning: This action removes the guardian from all of the student’s classes at your school, not just the classes you teach.
  1. Click the class.
  2. At the top, click People.
  3. Next to the student’s guardian’s name, click More Remove guardians.
    • If you only remove one guardian, click Remove.
    • If a student has multiple guardians, check the box for the guardian and click Remove.
When you remove a guardian, you, the removed guardian, and the student receive a confirmation email.

Then go through the invite a guardian process:

Your school administrator chooses who—verified teachers or administrators—has permission to invite and remove guardians. Only one person needs to invite the guardian. When a guardian accepts the invitation, the guardian’s email is linked to the student in all of their classes. All verified teachers and administrators can see the student’s guardian.
If you can’t invite or remove a guardian, contact your administrator for help. 
  1. Click the class.
  2. At the top, click People.
  3. Next to a student’s name, click Invite guardians.
  4. Enter a guardian’s email address.
    To invite multiple guardians, insert a comma between the email addresses.
  5. Click Invite.
If the guardian hasn’t accepted an invitation, you’ll see “(invited)” next to the guardian's email address. After a guardian accepts the invitation, you and their student receives a confirmation email. And, the guardian’s name shows next to the student’s name. For privacy, students don’t see the names of other students’ guardians.
