To notify parents and guardians about their child's upcoming work, you can enable the visibility of the 
Update alerts icon in the Brightspace Parent & Guardian web application. When visible, this icon indicates there are notifications for upcoming assignments and quizzes that are due in the next 2 days.
Note: This functionality only impacts the web application. Turning the configuration variable on or off does not affect notifications in the Brightspace Parent & Guardian app.
When parents and guardians log in to the Brightspace Parent & Guardian web application, the learner selector page displays the Update alerts icon, indicating there are upcoming assignments or quizzes for one or more learners.
Parents and guardians click the Update alerts icon, and then one of the notifications from the list. This navigates to that learner's dashboard, where the upcoming assignment or quiz is visible in the Work To Do widget.
To enable notifications in the Brightspace Parent & Guardian web application
- To enable visibility of the icon in the Brightspace Parent & Guardian web application, turn on the d2l.Tools.ParentPortal.Nav.ShowNotifications configuration variable. The default value is off.
Ensure that parents and guardians are enrolled in the org as a Parent/Guardian role; enrollment in the child’s courses are not required.
