Gifted Issues Discussion homepage Forums Identification, Testing & Assessment WIAT scores higher than WISC

Is it normal to WMI as the highest?

We have thought about buying stock in the 3m company . We buy dollar store tape these days lol

Miscba I am no expert by any means but I would say that the VCI has been profoundly impacted by the selective mutism and that it's possible even the other indexes have been impacted to some extent too given that she has a significant anxiety issue.

It's not the most common thing for WMI to be the highest from what I understand, but it's certainly an asset to have a strong WMI.

The WMI tests mostly involve parroting back letters and number, possibly re-ordering them first. So the ability to hear, hold and manipulate then spit back out increasing volumes of random data. This is something that your DD might not have much anxiety about getting "Correct", if she is good at it she may not have underperformed because she did not feel that there was any wrong answer. Where as the VCI is all about talking and the PRI tests might still trigger some anxiety because she has to make the right choice.

I would imagine that to have any hope of getting an accurate measure using a psychometric test it would probably need to be administered by someone your DD can talk to (relatively) well. Does she see a psychologist for the selective mutism? Could they be the one to (re)test her?

Her psychologist could do maybe Ravens? I did a online Ravens and tested 3 of my 4 children, they all got scores in the 130's. 1 child is a VSL and the other 2 are more all rounded capable and the oldest is higher VCI.My VSL also did similar testing with her behavioural optometrist and scored in the 95th percentile on the visual stuff, I am not sure a Ravens would be accepted at school so I don't know if testing would achieve much. From what I have read we would need to wait 12 -24 mths to do the WISC again so I am looking at the SBV.

I should have booked with DD's regular Psychologist initially, but at the time of booking she didn't have the tests so I booked with a Uni, hence why I am questioning the results.A week after I booked she was able to do them, I should have cancelled and gone with her.

DD3's PSI score was low too but she got 100% accuracy on what she did do, apparently her block design was high,I don't have the subtest scores so it could just be a token comment.

I don't know if it is relevant but DD's WIAT ranged from 36th - 99th percentile.

How different does a WISC need to be from the WIAT for the WISC to be not accurate?

According to DD's WISC she shouldn't be included in any extension activities.

PRI was only 110 (75th%), apparently she scored high in block design but I don't have the subtest scores atm. WIAT was for reading comp in the 99th, Maths comp was her lowest & written and oral comp around the samish. IRL Maths is perhaps her favoured subject, ie she does it for fun and reading is a chore, she does not read daily at home and hasn't ever,she will read at school, we thought she may have eye problems but all test reveal no probs.

I should add she didn't read until her first day of school, she was a fluent reader, she just needed what she perceived as permission to start. I didn't know she could read and she hadn't been taught, she instead taught herself.

Most things she learns quickly and she is poor to display knowledge, doesn't answer in class, won't ask questions has no desire to draw any attention to herself, she will answer in a limited format if asked directly.

In the past she has also avoided handing in work, likes to sneak to the background, hence why we have instead be concentrating on her anxiety issues.

Yes, getting more complete data would certainly help! Given the other issues, I'd take the testing with a grain of salt. Why were you testing at this point? Do you need the scores for something and would you do something different than you are now if her IQ fell around 130 or fell around 100?

I do know two kids whose parents have had them tested on the WISC who are high performers academically (in GT placements in school) who came out with IQ scores right around 100. Both of these kids had high scores on PSI and WMI and lower scores on PRI and VCI. The one whose mom has shared the most & who has tested twice on the WISC, found PRI to be the lowest with her dc. I've wondered in their instance if having high speed and good recall contribute to overachievement.

However, these kids don't have any other exceptionalities that would have likely supressed the IQ scores. I do think that it is possible for an avg or high avg kid with good supporting skills such as WMI and/or PSI to perform higher than would be expected given FSIQ. I wouldn't be sure that is your dd's case if you feel that it isn't, b/c you have a family hx of giftedness, and b/c she does have comorbidities, though.

I won't be able to get the WISC subtest score until early/mid next mth. I did ask for them but didn't get them. I have been waiting 2 mths for her assessment.

Yep reading composite was 99th, reading subtest - word reading 98th, reading comprehension 95th & pseeudoword decoding 92nd

Does that mean she is more likely to overachieve at a young age and achieve at level when she is older?

Would a higher score on Ravens than she got on the WISC PRI mean anything?

We tested mainly due to her SM, we wanted to know what impact it is having on her ability & performance. As her mum I feel she is not working at full capacity and I am very reluctant to extend her academically, imo she has enough on her plate socially to challenge her. I worry about overwhelming her as she is a non eater as well (food texture issues), she just shuts down and regresses, she takes a long time to adjust to new settings, new people & so on, school being easy has been advantageous to her anxiety issues. She has come ahead leaps and bounds socially and atm we are holding her back academically, or so we thought, but according to her assessment results we aren't.

I will go and read page 12 now.

Thankyou to everyone for your replies.

Can her Gai be worked out on her higher scores, WMI & PRI? Does it need to be lower than her FSIQ?

Just going through the table on page 12 atm

No, GAI can only use the PRI and VCI scores. I believe that the thought is that VCI and PRI correlate more with g while WMI and PSI are less g related and more related to supporting skills that allow the child to show that intelligence.

A child with a 130 GAI and a much lower FSIQ due to low WMI and/or PSI will likely present differently than a child with a FSIQ of 130, for instance b/c the kid with the FSIQ that high has both ability and the horsepower to show the ability. A kid with a high GAI who lacks that horsepower might have a harder time showing what s/he can do due to slower speed in getting it out, organizational skills, or having a hard time recalling, if we take WMI and PSI at their face value of measuring what they sound like they are.
