Gifted Issues Discussion homepage Forums Identification, Testing & Assessment Help with calculating GAI please (WISC-V)

Hello all,

I've been lurking for a while and really hate to make my first post a request for help, yet I'm still doing it! I was wondering if one of you very helpful test-knowledgeable people would calculate my DD8's GAI given her WISC-V scores. No personally identifying info here but please let me know if I need to edit my post.

The reason I'm curious about her GAI is that her WM score was so much lower than the rest of her results. Therefore, was there a significant impact on her resulting FSIQ? Given that she has a few 19s, is it possible that extended norms would have applied to her testing? I'm afraid I don't know much about how the extended norms work and there's not a lot of info on the internet about them for the WISC-V.

Thank you in advance for your help and thank you for all the wonderful posts I've been reading. This is an extraordinarily helpful crowd!

I'm away right now, so I can't calculate it at the moment, or respond in much depth, but I can say that it probably won't change much, as the low subtest is not included in the FSIQ calculation.

Welcome Corvidae.

These are excellent scores. You should apply for Davidson if you haven't done it.

Thank you aeh.

And thank you for the welcome ajinlove. I applied for Davidson at the end of June so I'm currently on tenterhooks wondering if the decision will come down today or tomorrow. I'm not getting much done as I obsessively check my email!

With this score, I don't see why they would not accept her to the program :-)

Corvidae- those are excellent scores! We also applied to DYS in June and are anxiously awaiting a response :-) Fingers crossed!

Good luck to you! Please let me know when you find out. Exciting stuff!

yay! We are in the same boat. We also applied in June and eager to get the results.

Hello Corvidae, and congratulations on those results! I do not have access to the GAI tables (although I have searched for them as well!), but here's what I know. You add vocab+similarities+matrix reasoning+figure weights+block design to get the GAI sum of scaled scores. Then you take that sum and enter it into Pearson's table to find the GAI.

I believe that on the WISC V, a sum of 84=GAI 144 and a sum of 87=GAI 148, so your child's sum of 90 would put her GAI very near, if not equal to, her FSIQ.

As for extended norms, there are folks here that know plenty more than I do about this, but it appears that they might be applicable in some sections.

Just got the email from DYS, that my son was accepted. Check your inboxes.
