I wouldn't be surprised if they slacked off before that. Oh, little Johnny is twitching in his seat. He must be at the frustration point..."It's okay if you can't answer any more Johnny, you did quite well!"
I know you moderated this in your later post, Dottie, but I just wanted to sneak in to say that I think this is the reason to be very clear about your goals for a test AND to see a tester experienced with GT testing.
We informed our tester that we thought DS6 might be a Davidson candidate, so she knew to take him as far as he could go.
Of course, if he hadn't had the achievement test scores first, we wouldn't have known to ask for this...and if you're testing to find out where the child is, you CAN'T really ask for this...
There is a certain irony to it, I'll admit!
