Tons? I am not so sure about that. Maybe if these kids live in Silicon Valley. But yes, I think you are right, a child can take off in reading, which is great, but this doesn't necessarily mean they are PG. As for math, you can't really self-teach in the same way as you can for reading.

I suspect the kids who are 2-3 grades ahead in math are significantly more than the PG cutoff, while kids reading a couple of grades ahead are much closer to the mean.


Makes sense.
