While the debate on the moral virtues of any particular form of grade distribution fascinates as cultural artifact, the variability of grading standards has a more practical consequence. As grades increasingly reflect an idiosyncratic and locally defined performance levels, their value for outside consumers of university products declines. Who knows what an ?A? in American History means? Is the A student one of the top 10 percent in the class or one of the top 50 percent?
Fuzziness in grading reflects a general fuzziness in defining clearly what we teach our students and what we expect of them. When asked to defend our grading practices by external observers
–parents, employers, graduate schools, or professional schools –our answers tend toward a vague if earnest exposition on the complexity of learning, the motivational differences in evaluation techniques, and the pedagogical value of learning over grading. All of this may well be true in some abstract sense, but our consumers find our explanations unpersuasive and on occasion misleading. –John V. Lombardi –Grade Inflation and Abdication (Inside Higher Ed)
