There are several ways to allow a teacher to monitor another teacher’s class without assigning them as a substitute. You may designate the teacher as a Co-Teacher for the class, or you can grant the appropriate permissions through the system’s settings to enable the teacher to view and monitor other teachers’ classes. You may also assign a teacher as a substitute teacher for the original teacher.

Assigning a teacher as a Substitute

The best way to allow a teacher to monitor another teacher's classes is by assigning the teacher as a substitute. Please follow the instructions found here: Substitute Teacher Schedules

Assigning as a Co-Teacher

To assign a teacher as a Co-Teacher in Classroom, please follow the following steps:

Navigate in Securly Classroom to Classes and search for the class you need to add the teacher to.
Click on the three dots in the upper right of the classes panel and select Class Settings.
Click the + sign in the Teachers area.
Search for the teacher.
Select the teacher.
Click Add
Click Save

Now the teacher has been added to the class and will be able to monitor the class.

Allowing teachers to monitor other teachers' classes via permissions.

You may allow teachers by role to View/Start Other Users' Classes in the permissions settings of Securly Classroom. Only an Organization Admin of the system may adjust these settings. Follow these steps:

In Securly Classroom, navigate to Settings > Permissions
In the Class Management section, enable View/Start Other Users' Classes for the role or roles that you wish.
Click Save in the upper right.

Now those roles will have permission to start and view other teachers' classes.
