Gifted Issues Discussion homepage Forums Identification, Testing & Assessment wisc-iv question

my daughter's score are \

VCI 49/138/99
PRI 46/133/99
WMI 27/120/91
PSI 26/118/88
FISQ/148/136/99
GAI:
SIMILARITIES: 16
VOCAB: 14
INFORMATION: 19

BLOCK DESIGN: 15
PICTURE CONCEPTS: 15
MATRIX REASONING: 19
TOTAL 97 = 149/99.99%

Question is psych did not calculate GAI on his evaluation, should I have him do this, and should she have extended ceilings since she hit the ceiling in two sub areas (the 2-19s)

TIA

I am not an expert but the GAI comes to 148. The tester probably didn't calculate it because it is right there with the FSIQ. Therefore no need to calculate it and include it on the reports.

Do you have achievement testing or a portfolio? The FSIQ is DYS level!


Nice scores

Curious as to why "information" rather than "comprehension" was administered.

GAI was probably not calculated because it is not significantly different than FSIQ.

When I looked at the technical report #4 online, the sum of scaled scores chart put a 97 at 146/99.9 percentile. Maybe they didn't report because the scores are similar and GAI doesn't added anything?
If you have the raw scores you can figure out whether the extended norms will make a difference. Our psych didn't use the extended norms because she didn't feel that they had been vetted enough (her opinion not mine). I asked the extended norm question here and someone calculated it for me. It raised my DD's PRI and her FSIQ by a few points but it didn't really make a difference. Either way, my DD, like your DD, already had a DYS IQ so I didn't feel like it was worth pursuing with the psych.

So is the full scale IQ the sum of the scaled scores, or the second number... It is confusing.

For the GAI I used a chart I found online...

Obviously I am not an expert!

I wasn't sure if the sum of scaled scores was the FSIQ or the second number (136)...

That is why I looked up the GAI

Not sure why he did the substitution, but he is actually one of the question developers for the test, & knows it quite well.

My daughter is 7 btw.

Oh, and I got the GAI from a chart online... I have no idea how to figure it out myself.

This is my 3rd attempt at a reply!! Hopefully it will post this time:

from what I understand, "to calculate the General Ability Sum of Scaled Scores. The General Ability Sum of Scaled Scores is the sum of scaled scores for three Verbal Comprehension subtests (i.e., Vocabulary, Comprehension, and Similarities) and three Perceptual Reasoning subtests (i.e., Block Design, Matrix Reasoning, and Picture Concepts).

I can see the discrepancy in the PRI, she actually had 4 subtests in PRI:

Test/scaled score/%

Block design/15/95
Picture concepts/15/95
Matrix reasoning/19/99.9
Picture completion/12/75 (I think this was a substituted test)

Her Verbal Comprehension tests were:

similarities/16/98
vocabulary/14/91
information/19/99.9

The tester is one of the test question developers for the test, and knows the test very well. Not sure why he did substitutions. My daughter was 6 years 7 months when the test was given, she is 10 months older now.

I guess I was interested in the GAI because:

"The practitioner may wish to consider using the GAI in a number of clinical situations, not limited to, but including the following:
• a significant and unusual discrepancy exists between VCI and WMI;
• a significant and unusual discrepancy exists between PRI and PSI;
• a significant and unusual discrepancy exists between WMI and PSI; or
• significant and unusual intersubtest scatter exists within WMI and/or PSI."

Still not sure how to calculate the GAI with the 4 subtests and I am not sure how he calculated the PRI..???

It worked!!

Thanks for the responses & help.

No, I have listed all the tests given in the two areas.

I am confused too. I took the original tests, plus verbal subtests to figure out the GAI.

sigh.

I think I will have to clarify this with the psychologist who administered the test. From everything I have read the rules state that the GAI is extrapolated from the 3 subtests in each area.

If you take :

Block design/15/95
Picture concepts/15/95
Matrix reasoning/19/99.9
= 49
Her Verbal Comprehension tests were:

similarities/16/98
vocabulary/14/91
information/19/99.9
49 + 49 = 98/98 which gives a GAI of 147/99.9
