"We do not release statistics on W grade-point averages so we can't speak to the accuracy of the information you have." That was a flack for Yale, but other Ivy League colleges-with the partial exception of Princeton-were equally reluctant to discuss their grading practices with The Economist. Are they trying to hide something? Perhaps. Stuart Rojstaczer, a critic of grade inflation, has estimated average grades over time by combining dozens of unofficial and official sources. The results are startling (see chart). In 1950, Mr Rojstaczer estimates, Harvard's average grade was a C-plus. An article from 2013 in the Harvard Crimson, a student news-paper, revealed that the median grade had soared to A-minus: the most commonly awarded grade is an A. The students may be much cleverer than before: the Ivies are no longer gentlemen's clubs for rich knuckleheads. But most probably, their marks mean less.
