Canvas Course Roles
Students
Students have the ability to view content, submit assignments, and participate in discussions and groups. Students can do much of what you'd expect them to be able to do.
Teachers
Teachers are basically course administrators and have nearly complete control over the course.
TAs
TAs are very similar to teachers in the sense of permissions, except TAs should not have access to SIS data. TAs are meant to help the teacher and provide support, so they can view, give and edit grades in the Gradebook.
Designers
Designers can create and edit course content, discussions, announcements, assignments, quizzes, and other content filled features. Designers cannot access or give grades.
Observers
Observers have the least amount of permissions. Essentially, they can view the course content, including the discussion board, and download files. They cannot participate in discussions nor submit assignments.
