> The thing about tracking is that it doesn't require more resources.

Hehe of course it does. You’re talking about more curriculums, more book and material acquisition, more teachers with more training, etc. And maybe lots of schools don’t have 6 different math classes.

> Gifted kids don’t need more resources.

Agreed! That’s maybe why some schools are focusing on the kids who do need more resources?

In fairness to your argument, I think “gifted” kids do need support though, it’s just that they are statistically better at either having it given to them outside of school, or of finding it on their own. What’s left is just a rather weak argument about not letting them get bored. Solving boredom should take a back seat to solving education for the less fortunate, IMO.
