Then, they grade a second essay, running it through the same process and grading model they had created for the first essay, recalibrating any necessary point adjustments. Eventually they find a model answer and grading system that all the graders can use. Although, grading may seem subjective for each grader, believe it or not, if fifteen graders grade the same exam using this calibrated point system, each grader will typically fall within five points of each other. This is to ensure fairness, equality, and eliminate personal subjectivity amongst anyone grading the exams. Any grader who’s scores are consistently more than five points off from all the other graders is typically removed.
