Blackboard LMS supports three grading modes that help with fairness, workload distribution, and consistency: anonymous grading, delegated grading, and parallel grading. You can use these independently or, in some cases, combine them for a single assessment.
Anonymous Grading
Student names are hidden while you grade and are only revealed after you post grades. Use this when you want to reduce the potential for bias from knowing whose work you're grading. Anonymous grading works with a single grader. It doesn't distribute or duplicate grading work.
Delegated Grading
Assign specific users (instructors, teaching assistants, or graders) to grade different sets of student submissions. Each delegated grader only sees the submissions assigned to them, and they grade independently; they don't see what other graders assigned. A designated final grader (usually the instructor) reviews the provisional grades and reconciles them into a final grade. Use this to split up grading work across a team, especially for large classes or merged courses where you might assign each grader a section.
Parallel Grading
Assign multiple graders to grade the same student submissions independently, without seeing each other's grades, feedback, rubrics, or file annotations. A reconciler then reviews all the independent grades and determines the final one. Use this when you want more than one perspective on the same piece of work to catch inconsistency or bias. Some institutions call this "blind grading." You can combine parallel grading with anonymous grading so graders also don't see student identities.
Difference between Delegated and Parallel Grading
Delegated and parallel grading both involve assigning multiple people to grade. The difference is whether graders grade for the same students or different students.
Delegated Grading | Parallel Grading | |
|---|---|---|
What each grader sees | A different subset of students | The same students as other graders |
Why you'd use it | Split up the workload across a team | Get more than one independent opinion on the same work |
Final grade decided by | A designated final grader, reconciling provisional grades | A reconciler, reviewing all independent grades |
Reconciling Grades
Both delegated grading and parallel grading rely on a reconciliation step, someone with reconciler privileges reviews the provisional grades and determines the final one students see.
