Since Nov., he has been working in epgy algebra and just sitting watching him with the example problems, it seems very clear to me that his ability to take in and ENJOY new/much harder mathematical material is pretty darn high and I think it would be a poor placement for him to be in pre-algebra next year
...
I am almost certainly going to appeal based on the algebra being technically 3 grade levels ahead of his current grade
. I feel it is absurd of the committee to have ignored this information because they probably thought they couldn't 'trust' it. 
Perfect. I'm so glad that you are taking this opportunity. I would say that you are correct in that they didn't give your information full weight. The purpose of the phone call is to detect what format they will be able to take this info in through. Do they need a video of your son doing the EPGY and seeing the obvious enjoyment? Ask the expert's help in translating your observations into demonstrable and impressive proof that they are used to dealing with.
Phone calls are hard, because they can't see your face and read your posture. You can overcome this to some extent by:
Getting completely dressed as you would for an in-person interview. Make up if you feel best in it. Shoes, too.
Take a few centering breaths and try to remember that the world is filled with good, caring people who want to do what's best for all children, and need your support to help them do what is best.
Try to do a lot of reflecting 'so what I hear you say is'
Take notes while she is talking, and mutter while you write. It helps her get that you are listening, and slows you down. Over the phone or speech rate is the most pertinent nonverbal.
Fast talking can sound like excited talking which can sound like negative emotion talking. Think Yoda. Think the Dali Lama. Those guys don't rush their speech.
I have had enough phone contact with Davidson Moms to venture that all most all of us 'talk much faster' than the regular population. Half the time
I find it hard to keep up!
Best Wishes, and may what's Right Prevail!
