I think the the psychologist didn't use the extended norms because as I understand it, you would usually need at least two subtests to ceiling...
"The extended norms are useful when a child�s score is the
maximum (ceiling) on two or more subtests (e.g., obtains scaled scores of 18
or 19 points)."
Is the same thing true of the SB-V? My son (5y3m at the time of the test) received scaled scores with two 19s and one 18 on the nonverbal domains, and two 19s and two more 18s on the verbal domains. Is there a similar effect where you can calculate a higher level for the subtest portions? I guess I assumed that the extended norms wouldn't apply because his overall FSIQ was 152, well below the "ceiling" of 160.
