As a teacher who claimed your school first on ClassTag, you automatically became the ClassTag Leader. After you have invited another school leader (i.e. - Administrator, Counselor) to take on the ClassTag Leader role it may eventually be time for you to remove yourself as ClassTag leader.
Please follow these steps:
1. Log in on ClassTag and click the three lines on the upper left side.
2. Go to "Account Settings."
3. Click "Schools & Classes" under "My Relationships."
4. Click the three dots next to the School name.
5. Click "Resign as a ClassTag Leader."
