Canvas Guides state, “To curve grades, Canvas asks for a median curve score and then adjusts the scores as a bell curve 66% around the median score. For instance, if the median score is the equivalent of a C, Canvas would distribute mostly C- and C+ scores, distributing outward down the curve to Bs and Ds, and then ultimately As and Fs. This type of scoring creates a predictable distribution, but it means that students will compete against their classmates for scoring.
To learn more about how curved grades are calculated, view the Curving Grades in Canvas PDF.
Note: Grade curving cannot be undone. Pre-curved grade histories will be available, but the curving action is irreversible.” Students are notified immediately when their grade is changed.
Based on the comments of other staff, caution should be used before curving grades.
