Why do people say "they'll all catch up eventually" when it's just not true?

[HailSatan]

If it were every child would come out of school with straight As. Theres always different tables or sets. Some kids just aren't academic either. So why do people lie?

Schools in my experience treat the parents of all children as though they don't really know their child, and are like the parent you mention. This is unfortunate if your child is genuinely not being challenged at school.

This was exactly my experience. I really feel for the parent who was just dismissed by the school. I have been that parent saying please listen, my child is ahead. I've even been told my child was not ahead, it was just that she did well in tests. Other times schools have gone well out of their way not to test her.
