Applications for Education
Altering your Google account profile image can assist with name acknowledgment so that parents begin to put a face with a name as soon as they begin receiving emails from you. They will not have to wait up until the first parent-teacher conference or open home night to make the association between your face and name.
If you have more than one instructor in your district with the exact same name or similar names (at one point there were 3 Mr. Burns and a Mr. Byrne in my district) students seeing an email with your profile image can visually validate that they are emailing the correct person.

When your school concerns you a Google Workspaces for Education account your profile photo will simply be a simple letter icon featuring your initials. Many people leave it that method just since they dont know how easy it is to alter it. In the video below I show
how to alter your Google profile image.
