I can't think of much to add except to ask how they deal with certain asynchronous development issues (e.g., handwriting). In our local school, it seemed that they were holding DS back in math because he wouldn't be able to keep up with the writing. We have since changed to a school for HG kids, and although they help work on handwriting issues, they do not consider it a reason to hold my kid back.
Good point about asynchronous development...right now my DS is somewhat held back in reading b/c his writing is more age typical. They do scribe for him, but they're pushing him to finish the DRA level 28 (end of 2nd grade reading) himself which requires a significant amount of writing. His actual reading level is more like end of 3rd, beginning of 4th, but they're so focused on getting him to write his own summaries that he rarely gets to read that stuff at school. They will scribe for him sometimes, but not as often as I would like.
Right now, we're definitely leaning towards the full time gifted program. I get to visit on Wednesday and I'm looking forward to it.
Thanks again
