You’ll need to make sure you have the right permission to edit a teacher's details. The Access Coordinator may edit a Teacher or Teacher Admin record; a Teacher Admin may edit a Teacher record.
First, ensure you are in the green Teachers tab of the Admin Hub. Select the teacher account you wish to edit, to highlight it. Then, select 'View teacher' at the bottom right hand corner of the screen:
You can then edit the teacher account details:
If your edits include a change to the email address for that account, an email will be sent to the new address and the change won't be made until the user clicks on the generated link within that email to verify the change.
Once you have finished editing the teacher account, click OK to ensure your changes are updated.
