Quizplus · Accepted Answer

Asking a colleague to re-grade a set of essay questions is a method often used to address concerns about rater error, which refers to inconsistency or subjectivity in grading. By having a second rater or grader review the same set of essays, the professor can get a better sense of the validity and reliability of the grading process. This can help to ensure fairness, accuracy, and consistency in evaluating student performance.
