A seguito di quella che è definita “l’inflazione dei voti scolastici”, in America moltissime università stanno imponendo dei limiti alla media, mentre alcune hanno addirittura eliminato totalmente i voti. Il Regno Unito, invece, ha scelto un approccio totalmente differente che sembra funzionare.

Grading can feel like the cruelest part of the semester for teachers and students alike. And no one seems to have quite gotten it right. Commentary on grading brings to mind the story of Goldilocks and the Three Bears. Like the porridge that is too hot or too cold or the bed that is too big or too small, grading policies are either too lenient or too harsh. Top U.S. universities have come under fire in recent years for grade inflation. A grades have been the most common grade at Harvard for 20 years, and the median grade there today is an A-. There's even a website that has tracked grade inflation in American schools and universities over time.

On the other end of the scale, France is currently figuring out how to reform a high school system that gives out overly punitive grades. A 16 out of 20 on a baccalauréat exam is currently an exceptionally high result.
