Thanks a lot. I don't think any of that will honestly sway the local school-- it's not that they are unaware of acceleration options, it's that they simply are entrenched in their way of doing things. I already brought up a lot of stuff that's cited in that article.
After some review of the NH administrative rules of the department of education, I may have a plan of attack. There are rules which can make a compelling argument that they're required to teach new material to any child, and we can also apply for a hardship determination at the state level that might put some helpful focus on the situation and get them to change their position, and could let us also take him to a school in another district.
