As mentioned in the preparation module, rubrics do not transfer to Blackboard. Within the prep modules, you were asked to back up your rubrics in D2L and can now recreate them in Blackboard.
Moreover, rubrics do not exists within their own separate tool in the Blackboard course environment. Instead, the “Add Grading Rubric” function is an option within the settings of several assessment types within a Blackboard course.
To add a rubric, you will either have to create them within the gradebook or add them to a new or existing assignment, discussion or journal. As long as grading is enabled, you will be able to add a rubric.
