Teachers can set student avatars, instead of behavior characters. When this mode is enabled, milestones will not be shown at all. Here's how.
- Open the class from the left menu.
- Click on the Behavior tab from the Updates icon.
- Click on the More... link.
- Choose Settings.
- Under Theme, click the option.
- Choose Student Avatars.
- Your behavior page now shows student avatars, instead of characters.
PS: When Student Avatars is enabled, class goals are disabled.
