Canvas now provides an administrative switch that will prevent teachers from modifying course availability dates. However, even when this switch is selected, instructors using the “Adjust events and due dates” option when importing course content can override the term dates. To make it worse, if the “Do not allow teachers to modify course availability dates” is turned on, the instructors are not able to change from incorrect course dates to the term dates. I would like to suggest that Canvas allows instructors to adjust course dates, but after the adjustment is made, the term dates would be automatically selected instead of the course dates. The colleges could then use or not use the switch that prevents the instructor from changing the course dates.
