You can share rubrics between Blackboard Learn courses. If you teach multiple courses, you can create a rubric in one course, export it, and then import it into another. You can also share the exported file with other instructors to use in their Blackboard Learn courses.
You need to make all changes to rubrics inside a Blackboard Learn course. Don't make changes to the exported ZIP file.
Control Panel > Course Tools > Rubrics
To import a rubric, select Import Rubric and browse for the file. Select Submit to upload the file.
To export a rubric, select the check box next to the rubric's title and select Export. You can save it to your computer or the Content Collection if you have access to it.
