Daughter's scores are at the bottom of this post. There appears to be a discrepancy between the statement on the NAGC website and the WISC technical bulletin, see quotes from each below.
Thank you so much for your help and insight. Our daughter's neuropsychologist did not do the extended scoring because she only had 19 in one subtest, similarities. Her tester said that our daughter needed to have more than one 19 to apply extended scoring. The neuropsychologist said she did not see scores like this very often, but said extended scoring was not warranted.
Here is what NAGC's website says:
"Despite these limitations, testers should consult the Extended Norms if a child achieves at least one scaled score of 19 or two of 18 and modify scaled, Composite, GAI and Full Scale IQ scores accordingly. These can be found in Technical Report #7, available at
http://www.pearsonassessments.com/N...C-8E4A114F7E1F/0/WISCIV_TechReport_7.pdf or through a search for �WISC-IV Extended Norms.� "
That bulletin in the link states that extended scoring is useful when a child has the ceiling score of 18 or 19 for two or more subtests.
What do you think? The test is over a year old.
