Grades aren’t valid, reliable, or objective. A B in English says nothing about what a student can do, what she understands, where she needs help. Moreover, the basis for that grade is as subjective as the result is uninformative. A teacher can meticulously record scores for one test or assignment after another, eventually calculating averages down to a hundredth of a percentage point, but that doesn’t change the arbitrariness of each of these individual marks. Even the score on a math test is largely a reflection of how the test was written: what skills the teacher decided to assess, what kinds of questions happened to be left out, and how many points each section was “worth.”
