I said I can judge your kids better
relative to other kids because I have
extensive experience doing it. If you think
you can do that better without any experience actually evaluating kids, then I think it's
you who needs the reality check. It's such hubris to think you can do the job of an experienced professional better without any experience or training whatsoever, and that's the whole problem with busybody parents.
The few sentences you provided are highly correlated with very successful students. Learning Latin in 5th grade is not something 90% of children do. Immediately your kid stands apart for having done that. Same with sports and music. Combine that with good grades, and that's the profile of a top student. What more do you want? Again, what's your conception of a top student, and how do your kids not qualify? Is it because they're not getting straight A's?
Still so wild to me that you, as a father, are arguing post after post to me, a dog on the internet, that your kids are below average. I mean, regardless of what reality I live in, what's up with that? Who are you really trying to convince here?
