We're not funding education so that the talented ones can be identified and elevated. We're finding it so that the others can be helped to grow. Latent academic ability at age 8 is a pretty small slice of the task.
The ranking of academic performance at 8 years old remained stable for the next 10 years. Not just the top.
If teaching had a positive effect then why would that be stable? That implies that there was no difference caused by course choices, nurturing by a better teacher, etc. so where is the growth?
And that’s my anecdote. Some studies indicate you can probably skip a decade and show up to college and catch up to your peers in no time.
I don’t think I believe instruction cannot give you useful information, but that the 3rd-12th grade knowledge is thin, artificial, and non-transferable.
I see a lot of growth among high schoolers (my wife is a teacher and I volunteer in the math center at the public school where she works, so I have a lot of contact with them). I also experienced it myself. My shift from picking locks (with mischeif in mind) to an enthusiasm for math and science was mediated by four or five great teachers.

That might be true, but it comes at a cost which is that the first two years of college are just high school again.
I've been taking college classes for the last 20 years (most of it far less than full time). It's a bit of a hobby. Every time I switch majors I have to slog through this barrier of classes full of things I already know before I can get on to the good stuff. It's a really stark transition, after which the instructors start treating you like you're there to learn instead of like you're there to score points in some status game.
I always end up with really close relationships with the instructors when I'm wading through highschool 2.0 because they're usually pretty happy to have somebody asking questions about the content and not about what's going to be on the test and when I talk to them about this problem they tell me that they've had to realign the curriculum downward because there's a bunch of stuff which they can no longer rely on high school to teach.
So yeah, is broken. But it didn't used to be broken. Do you really think the way to fix it is to further lower our expectations about what can be usefully done in k-12?
Exempting charter schools from curricular oversight and letting them figure it out (or not) amongst themselves is only going to make for an even wider band of preparedness among college freshmen, which correlates with an even longer slog through highschool 2.0 while the colleges now do even more of the level-setting work that the highschools used to do. That makes the classes more boring, which make college a less attractive option. Plus the taxpayers aren't getting what they're paying for. It's a lose lose scenario.
