How do I prevent students from switching groups in self sign-up Groups?
Canvas recently introduced a new page design called the New Canvas User Interface (UI). Depending on your Canvas view, your page design may vary from the images shown in this lesson. However, the functionality and location of the components remain the same.
When self sign-up is enabled for a group, instructors are unable to prevent students from switching groups. However, as an instructor, you can turn off the self sign-up at any time. By turning off the self sign-up, you prevent students from switching groups.
