Tim Harford's solution to grade inflation
From the Financial Times, 3/20:
The obvious solution to grade distortion is to ration grades so that no matter whether standards are high or low, only the better students can receive the top grades. Unfortunately, like any competitive system, such policies can create ill-feeling towards high-flyers, and even sabotage.
If grade rationing is unacceptable, perhaps grade distortion should be replaced with true grade inflation, freeing grades from the worldly confines of a maximum 100 per cent or A*.
