DS5's teacher is simply encouraging him to read widely, and I think that's entirely appropriate, so yes, I'm happy. Sometimes she gives him particular books to read, sometimes she suggests things, sometimes she just lets him loose in the library. (Whether DS5 would test at highschool reading level would probably depend on the test. At any rate, he happily reads science writing aimed at adults, so I imagine he's the kind of child you're thinking of: it's always been obvious that there was no need for anybody to try to teach him to read!)
His writing, OTOH, is more or less normally developing and the instruction he's getting on that side is the same as for his classmates, which again is appropriate. (Very little connection between the teaching of reading and of writing at this age, of course: they did get to take in a favourite book in order to write something about it once, but otherwise the two are pretty separate, which suits DS well right now.)
Spelling: he gets short lists of words to learn, mostly comprising the words he mis-spelt in his written work, and he evidently takes part in some phonics activities, but I don't know much about what they do.
Does that help? I wasn't very sure what you were getting at - surely nobody attempts to teach children to read if they're that far ahead? Yet high reading achievement doesn't necessarily go together with high writing achievement, particularly in the early years where motor skills can be limiting.
