“…An early 20th-century text on grading systems, for example, laments that the "variability in the marks given for the same subject and to the same pupils by different instructors" causes "real injustice" for students (Finklestein, 1913, p. 6). Current research on grading practices continues to explore variability, not only across institutions and educational systems, but also between teachers in the same system (Biberman-Shalev, Sabbagh, Resh, & Kramarski, 2011;Proitz, 2013;Randall & Engelhard, 2010;Resh, 2009). Grade inflation, the phenomenon of grade point averages rising without commensurate increases in achievement, is another area of ongoing research (Organisation for Economic Co-operation and Development, 2012;Pattison, Grodsky, & Muller, 2013).…”
