In Blackboard Ultra once a rubric is associated with an assignment, the rubric is available for students to view.

Students can view a rubric before they open an assignment, test, or discussion and after they start the attempt. Students select This item is graded with a rubric to view the rubric.

This is how students view a rubric before they open a gradable item or after they start the attempt.

Students can view the rubric alongside the instructions. They can expand each rubric criterion to view the achievement levels and organize their efforts to meet the requirements of the graded work.

This is how students view any given rubric criteria on a gradable item.
