I was wondering what the benefit of having the SB5 extended norms calculated is? Is it to try and distinguish between extremely and profoundly gifted? In what ways is it useful?
thanks

It's similar to the WISC-IV extended norms: it is an attempt to spread the curve above the 99th %ile, to distinguish between HG, EG, and PG.

With a fsiq of 154 and hitting 6 ceilings, do you think it is worthwhile asking the psych to calculate it? I'm already blown away by that result!

Yes.

This is my first time posting - I have been lurking and reading the last 6 months but I really wanted to ask more about this particular question. Has anyone had the SBV extended norms used as part of the assessment and did using them yield anything above 160? I'm curious because my DS also got a FSIQ of 154 with multiple ceilings on the SBV but the testing psyc didn't say anything about using the extended norms - and she specialises in testing gifted children and has done a lot of testing with the SBV over the years.

Her website did say that they use the extended norms in very rare circumstances but at the time DS was testing I was still doing a lot of research and felt too silly to ask about the extended norms - but I wish I had. But as far as I know the extended norms on the SBV don't yield much higher results - although I have heard of someone who got a very high Iq score using the WISCivextended norms.

So if you did ask the psyc about this jayta, I would be very interested to hear what they say!

It depends on how far above the subtest ceiling the child scored. If it's only a few points, then, no, it probably won't make much of a difference. But you can't know that without access to the norm tables.

Tippy I think I may have used the same psych as you. I just shot them an email and had the EXIQ within a day. The report was modified to include it as well.

It came back as 163 - so 9 points higher than the FSIQ. I don't think that makes a huge amount of difference? I'm not really sure. I am quite thankful though that it wasn't any higher!

If you are in Sydney it must be the same psyc Jayta. And it's interesting the psyc then used the extended norms but only at your request. I guess though that if the extended norms on the SB5 never give a much higher score than 160 for anyone then it's not possible to distinguish between exceptionally and profoundly gifted using the SB5 - at least in the way it was possible with the Stanford Binet l-m?

And I know what you mean that you are grateful the score wasn't much higher - but once you get to > 99.9th percentile I think that is pretty extreme anyhow! My DS started school this year and things have been pretty tough and we are having all sorts of issues at school and home - from trying to get school work at the right level to extremely selective eating, and things just seem to be constantly getting worse. We are going to start counselling for DS soon and hopefully that will help.

Actually, the top score on the ExIQ is 225.

I have read that the exiq on the SB5 has a theoretical upper limit of 225 - but nowhere have I seen or heard of anyone actually getting a score much above 160. The SB5 was supposed to have a much higher ceiling than the SB4 but once they developed it and tested it using a group of exceptionally/ profoundly gifted children they found that it in fact depressed scores even more. Then they developed the Exiq for the SB5 to address the ceiling issues - but what I'm wondering is if it has in fact solved the issue - not just in theory. I guess if I have any more dealings in the future with the testing psyc I can ask her the question directly since she has done a huge amount of testing with it.....

Yes the EXIQ scores can go really high, so I guess DD only went a little above the ceiling.

Tippy I hope the counselling helps your son. I have heard there a few public schools in the Sydney area that are really good with gifted kids. I'm not sure if you have looked into those?

We are trying to decide whether to early enter or not atm.

Jayta we did early enter DS into a public school - and we had a meeting with them at the end of last year prior to him starting. They were very supportive and open to acceleration etc eventhough they have never dealt with an exceptionally gifted child. He so far has somewhat been accelerated subject-wise but he isn't cooperating too much with the teacher and socially things really are not going too well. DS is really into strategy games and his teacher said he is very different to the other children, so academically and socially it really can't hurt to accelerate him. But we have run into some unexpected problems at school due to sensory issues and fears that he has. So really we are desperate to get this counselling going so we can make things better for him at school.

We have heard of a school that is good with gifted kids but DS has an older sister at his school already who is highly gifted - with a more uneven profile. But she has a couple of very good friendships at this school - and it will be very hard for me to have them at different schools (with getting them to and from school).
So I have to weigh up trying to make things work at this school for DS versus disrupting his older sister and making her move schools too. She already has anxiety issues so I really don't want to disrupt her.

Good luck with your decision to early enter or not - we really felt we had to send DS to school early as he was completely fed up with the boredom of preschool and "baby stuff".

So she's in the attic, not the roof?

It's just a pity there are so few people up there.

145 is PG according to Davidson and Hoagies.

Tallulah - it is confusing because in Australia it seems 145+ (Or > 99.9th percentile) is classified as exceptionally gifted and the term profoundly gifted isn't used - perhaps because the newer Iq tests won't differentiate much beyond 160. It probably doesn't matter anyhow but I still feel a bit curious about the usefulness of the Extended IQ.t

that is a good way to put it
