You can add and manage the co-teachers who have access to your small-group assignments. A co-teacher can do anything to the assignment except delete it or add to/edit its co-teachers.
The co-teachers on a class do not automatically see individual/small-group assignments for students in the classes that the two of you co-teach. Instead, the primary teacher can control the co-teacher(s) who have access to the small group assignment directly from the create and edit small group assignment windows.
When creating an individual/small group assignment, a new field will appear that lets you add a co-teacher to the list. The co-teachers you can choose from are only those that you share at least one class with. A small group assignment is owned by whoever creates it, even if that person is normally a secondary teacher of the class the students are in.
After you create an assignment, you can add or remove co-teachers on that assignment from the Edit Assignment window. To get there, click the pencil icon in the top-right corner of the assignment on your Assignments page (or on the Assignment Dashboard). At the bottom, you will see the option to add or remove co-teachers.
If a co-teacher leaves or is removed from your class and you no longer share any classes, they will still be shared on small group assignments. You can remove them from small group assignments using the Edit Assignment window. If you no longer share any classes, you will not be able to add them back.
Small group assignments are owned by faculty memberships in a school, rather than by classes. If a co-teacher leaves your school, CommonLit will remove their access to any small-group assignments you've shared with them. If you move schools, you will lose access to all small group assignments at your former school; if any of them have co-teachers still in the former school, CommonLit will transfer over ownership of those small group assignments to one of the remaining co-teachers.
