This is one of those issues that I can't understand the opposing argument. It's just an issue I find so objectionable that I cannot understand why anyone would be imposing this. Literally holding kids back.

The only defense I hear is that kids don't really benefit from advanced classes and they'll be fine anyway. But gifted children will not necessarily be fine. Most of the smartest people I know struggled in school just, but most were fortunately saved by advanced placement classes that put them in classes where they can learn at a faster pace than the rest of the children. Were they forced to stay in what to them amounted to remedial classes, they would grow to resent education and actually underperform.

The utter disregard the people pushing these policies have for children is appalling. Hopefully this is just a weird time in our countries history where that we'll look back on and think how absurd the policies were.
