How do I share a New Quizzes item bank from a course with an account?
As a Canvas account admin, you can share a New Quizzes item bank from a course with your entire account. If a sub-account admin shares an item bank with the account, the item bank is accessible by the entire account.
Note: In order to view all account item banks, users must have the Item Banks - account manage permission.
