A parent/observer must first have an observer account in Canvas. Users can create an account manually or sometimes, the institution will create accounts for observers. When that's done, a student-specific pairing code will need to be generated to link the student and parent/observer's account. Students can generate pairing codes from their User Settings. Depending on school permissions, admins and instructors may also be able to generate pairing codes. For more information on pairing codes, check out How do I link a student to my user account as an observer? and Pairing Codes - Frequently Asked Questions PDF.
