I'm definitely for answering it honestly -- we always have, but then the school already knew about DS because they gave him the WJIII at the end of preschool. The worst that can happen is they won't believe you and will totally ignore it (assuming that they wouldn't stoop so low as to actually hold it against him in a gifted school), but if you don't answer honestly, it could be held against you in later years of advocating. "Why didn't you mention anything like this when he started school?"

They asked for it, give it to'em.
