• With a rubric, you know exactly what to look for in every paper you grade, so there's no need to spend too much precious time reading each essay for correctness. A rubric allows you to identify what is important in an assignment, judge how well the student met this standard, and assign points accordingly. After you've done this for each element on your rubric, all that's left to do is to add the points together. Then, you've got the student's grade figured out for you.
