Applications for Education
Changing your Google account profile image can assist with name recognition so that parents begin to put a face with a name as soon as they begin receiving emails from you. They wont have to wait till the first parent-teacher conference or open house night to make the association in between your face and name.
If you have more than one teacher in your district with the very same name or comparable names (at one point there were three Mr. Burns and a Mr. Byrne in my district) students seeing an email with your profile picture can aesthetically validate that they are emailing the correct person.

When your school issues you a Google Workspaces for Education account your profile image will simply be a basic letter icon featuring your initials. Because they dont know how easy it is to alter it, lots of individuals leave it that method only. In the video below I demonstrate
how to change your Google profile image.
