I couldn't remember the whole back story, so I went back and looked at some of your prior posts. It appears that you've been banging your head against a wall and getting nowhere with your ds' school in terms of better educational placement. I have a couple of thoughts/ideas:
* Did you ever get anywhere with the school GT person? I.e. - did the school do any testing or agree to group him differently based on his MAPS and AR scores? Did s/he respond to you at all other than saying that s/he would work with the classroom teacher?
* I think that giving specifics as to what you want them to do is always good. I would put in writing a request and not just have it say that you want him to be challenged. I would specifically ask to have him go to the first or second grade classroom for part of the day for language arts instruction and/or math instruction. Attach whatever support you have: his MAPS scores are good b/c you can not only show that he was at the 99th for kindergarteners on reading and 93rd for math, but what those same scores would be as compared to 1st graders. If he is performing in the top 25% of the 1st graders, there is no reason that he cannot take class with them for that subject.
Second grade language arts would require a lot more writing than 1st and is a bigger request, so you might want to start with asking for him to go to first grade for both subjects.
* Maybe request a meeting to discuss and cc the principal and possibly the district GT coordinator.
* Call the district GT coordinator, explain what you have been dealing with and the test scores that you currently have for your ds and ask what they can suggest.
