Why is grading often a challenge? Because grades are used as evaluations of student work, it’s important that grades accurately reflect the quality of student work and that student work is graded fairly. Grading with accuracy and fairness can take a lot of time, which is often in short supply for college instructors. Students who aren’t satisfied with their grades can sometimes protest their grades in ways that cause headaches for instructors. Also, some instructors find that their students’ focus or even their own focus on assigning numbers to student work gets in the way of promoting actual learning.
