Dear Ariadia,

After kindergarten screening, do they intend to do a full diagnostics (IQ)on him? If not, it might be something for you to pursue independently. With that, you might consider grade skipping (I've found the younger you do it, the easier it is for the kid).

My personal philosophy is that you should work tirelessly with the school administrators in a non-adversarial manner to negotiate what you want...and THEN threaten to sue (half-joking).
