Grading Grades

Wednesday, April 25 2007 by

If one professor’s "A" is another professor’s "C," then what exactly is a grade point average measuring? It’s a question at the center of the debate over the Achievement Index, a new evaluation scale under consideration at the University of North Carolina at Chapel Hill. Peter Gordon, psychology professor and chair of the UNC-CH faculty committee on grading; and Howard Aldrich, professor and chair of the sociology department, join host Frank Stasio to discuss the statistical and philosophical merits of grade point average and its alternatives.
