Grade Centre Overview
The Blackboard Grade Center resembles a spreadsheet. Each row represents a user in your course and each column includes information for assessment items such as an assignment, test, graded blog entry, or survey. This is where you access your student submissions for grading.
You can provide grades and comments directly on the Grade Center page, on the Grade Details page.
You are able to customize your view of the Grade Center and create grading schemas, grading periods, categories, and columns to present and gather the information you need.
Access the Grade Center
You access the Grade Center from the Control Panel. Expand the Grade Center section to display the links to the Needs Grading page, the Full Grade Center, and the smart views.
