After looking at the extended norms technical report, it doesn't seem like he was at the absolute top for any of the sections, even though he had a 19 and some 18/17s. I read somewhere that if the child has more than two scores of 18 or higher, the extended norms should be used...but that doesn't really make any sense.
Why would ext norms be used it the ceiling wasn't hit?

I guess I don't really have an understanding of how the test works, so perhaps I'm missing something.

A little confused why the doctor would tell us that he "topped out" on several subtests. Details. But I still want to get the clear picture. He's my kid, so I figure that's reason enough to want to know.
