If you asked nicely, would your school do IQ and achievement testing?
As far as being ahead in reading English, are his parent's English speakers? If so, it's hard to know how impressed to be - most gifted kids don't get much out of their classroom experiences in reading in the first place, so I would guess that for majority of gifted kids, they are self taught in reading.
We have 4 language immersion schools a stone's throw from us and I know many kids that attend them. For bright kids that have an involved family that speaks and reads English in the home, I wouldn't consider this that remarkable. Most of the language immersion kids I know are reading English well by the time their school gets around to introducing it. If his family are not native English speakers, that would make a big difference.
I think it's wonderful this child has such a dedicated teacher though!
If he is surrounded by kids not as high achieving, it would definitely be great to find something to challenge him. I would definitely talk to the parents and feel out that situation. If his parents are happy and he's happy in the classroom, maybe they are doing additional enrichment at home? I'd perhaps lay all this out to them.
