Read-only is the state of a Canvas course after the participation end date has passed. This date can be proactively changed by the instructor before it passes. After the end date passes, contact the Canvas administrator to request a change.
Read-only for students: Students can see all materials and grades but are unable to post, submit, or interact with the course, teacher, or students in any way.
Read-only for instructors: Instructors can see all materials and copy them to another course, view grades, and manage course files, but are unable to make edits to pages, discussions, announcements, assignments, quizzes, grades, settings, or add new users.
Read-only for guests: This can be set up through the Observer role, another type of read-only role. Enrolling a guest with an observer role allows access to the course without being able to affect any course data or participation. When paired with a student, this role cannot submit work on behalf of the students they observe, but they can see student grades, assignments and events, and course interactions. Instructors can generate a pairing code for a student or link a student to an observer in a Canvas course.
Important Note: If you collaborate with other instructors on courses, you can only add them to your course before the participation end date passes. Once a course end date passes, you can request assistance from the Canvas administrator.
