Noam Chomsky went to a Deweyite high school with no grading and turned out more than fine (he actually enjoyed it). I am opposed to grading, I would replace it with a levelling system - you would have to show certain proficiency to gain a level.
All exceptional people are exactly that — exceptions. What happened to his peers?
There's almost nothing that can be learned from someone like Noam Chomsky that is applicable to the median student.
I think that’s a great idea. I’m not necessarily advocating for a strict grading scale, just an objective yardstick for gauging progress towards achieving proficiency in critical subjects like math, language arts, etc.
