Thanks!
I met with teacher and gifted coordinator in February. They are aware of his scores. They see his IQ but not any disability or challenges. They have theories to explain underachievement

most are maturity based...but age appropriate maturity

I asked about school's policy and history with acceleration. Gifted teacher took me off line appropriately as I opened it up as a future discussion. She emailed me several times since that she was researching and it appeared the policy is evolving at district level. I got an email last week that she wants to meet early May with vice principal to discuss and that the VP wants to share with me her thoughts on acceleration. I interpret this move as policy allows, school has negative opinion on it.
I am in no hurry as I think I want to learn, open the door and perhaps
Have them agree to end of year test him to see where he really is at by their own standards.
