I'll be happy for DD to be graded against the rest of her class when she's at school. I think it makes more sense to see where someone is in the spectrum than within themselves in an academic thing. Individual merits and improvements are for hobbies.

When a child enters the job market (which school is supposed to prepare them for) they need to realise they're up against everyone else, competing for jobs. Employers aren't going to say "well, you're not qualified but you're improving so i'll hire you"!
