Good Afternoon @econleyshannon!
Thank you for your post. At this time assignments can only be graded by points, percent, collected only or the main grade scale of the course. The closest equivalent to mastery paths in Canvas would be to grade based on total points. The available ways to grade assignments can be found here: https://docs.powerschool.com/UCHT/settings-sign-out/standards-grades-calculations/grade-calculation-...
Hope this helps and thank you for your feedback!
