We are wanting parents to ONLY go to our SIS Parent Portal to look at student grades. I know that i can disable the option for viewing total grades, but can I disable the option to view grades in Canvas at all? I'd love to be able to tell parents they can see due dates, and assignment information in Canvas, but no grades. That way they'd have no option but to go to the SIS parent portal. Is this possible at all? Thank you in advance.
