Answer: If you’re enrolled in a class that is being taught with Canvas, you’ll gain access to your class site on the first day of the quarter. Refer to the Academic Calendar for specific quarter start dates.
Answer: Features inside Canvas are managed directly by your instructor, so always contact your teacher first. It’s possible your instructor has chosen to disable a feature or has not opened up access to a specific feature inside the site. This is a good practice even when you suspect the issue is with the system–this ensures your instructor knows you’re having problems and cannot access the materials. Usually instructors provide contact information in their syllabus or directly on the site, however if you do not have this information, you may look it up online using our Employee Directory.
Answer: If it’s after the first day of the quarter and you’re still not seeing your course displayed inside Canvas, check with your instructor. Teachers have the option to publish their Canvas course site any time-even if it’s delayed past the first day of the quarter. Contact your instructor and let he or she know you cannot access the site. If your instructor believes the site should be available to you and you’re still having problems, please contact us at the Help Desk by submitting a ticket, calling or dropping by N250.
