Currently, Top Hat does not allow users to use a single email account for both a Student and Instructor account. Users can only have one account, which is decided when they first sign up. For example, if they sign up with a student account, they cannot have an educator account, and vice versa.
Best Practice: If the user is both a student and an instructor, they should choose a student account to continue to do their classwork. If you are both an instructor and a student, contact ITAC for assistance with creating your instructor course.
