That doesn’t explain why they don’t let her receive math instruction with a different class. The teacher is already teaching the content, my child is just not in the room.

It also doesn’t explain why she can only use the math app at her grade level or one above. They are rate limiting her.

When I was in sixth grade my parents convinced my (private) school to allow me to join the ninth/tenth grader's Geometry class. Two problems developed:

1. The material wasn't challenging; I didn't grasp what the point of "proving" a bunch of obvious stuff was, although I was willing to go through the motions. So I was an 11-year-old smart aleck in a room filled with 14 year olds who found me annoying (because, truthfully, I was super annoying at that age!). This contributed to:

2. The 14 year olds were super mean to me, AND they basically revolted against the teacher when I was in the classroom

In the end the teacher was happy to just privately tutor me, which was kind of her, but I have to acknowledge that I was genuinely disruptive to her class.

So I think there are real repercussions to allowing socially undeveloped kids into a classroom filled with kids at a very different (social) level.

There might have been a different outcome if I'd been in a school with a larger pool of moderately-to-very-gifted-at-math kids.

The next year my parents sent me to a school that had an agreement with the local university to send kids gifted at math to take university classes. The college kids were much more tolerant of me as a curiosity (and I was actually challenged, so I didn't spend my time annoying anyone, which probably helped, too).

They don't care about her learning. It's a school, she's not being tutored. It's mostly about childcare and ranking, not learning and they know her rank. If you don't ask for an individualised education plan or otherwise show that you know the magic words that show that you are preparing evidence to sue them they're not going to do anything.

Education schools have been very clear for decades that acceleration and other accomodations for gifted students are wrong and evil.

The point of gifted classes isn't to teach you better math. It's to separate the kids who are too nerdy to survive in the same class as normal ones or who behave too "gifted kid" all the time to keep a class on track.

If you want to be a tiger parent, do what the tiger parents do and send them to afterschool programs. (well that's what I think they do anyway.)

That is definitely true but I would suggest that it is a societal choice about basic values that makes it so. I'm not saying I personally disagree with that choice but we should see it as one rather than just the obvious.

Schools could be like other institutions which focus their attention and assess themselves based on the best they produce. Even some schools are like this (or American schools anyway) with sports. Is Coach worrying about how good the average student is at basketball, or the lowest quartile? I think not.

We have decided that it is essential that everyone reaches a minimum level, that the average performance should reach a certain level and that these two things are very important and much more so than making sure that the very best students can reach their maximum level.

Again, I'm not saying I think that is wrong. In a democracy, it has a lot going for it, but it isn't the only way to run a society either.
