I was not in the room when testing was conducted at by the gifted and talented department of the nearby university. I was, however, only about 10 feet outside the room, which had clear glass near the bottom (so I could see a bit of what was going on, but my child couldn't see me). I know him well enough to know that my presence would Not Have Been Helpful. lol. He would have been trying to get me react instead of paying attention.

He had pretty frequent breaks at which I saw him, offered snacks, etc.
