hi all,
i just looked at the DYS qualification criteria and noticed that it allows the GAI for WISC. I had sworn when i checked a few months ago, GAI was not listed. Does anyone know if thats a recent addition/change to their criteria or did i miss it before?
irene

You're right. That's new. I think it's a good thing

Is there a way to calculate the GAI if you do not have the subtests? Unfortunately I only have a few of the subtests and my son struggles so much with writing that doing a retest is probably out of the question. His psychologist suggested a retest to get a better assessment.

Here is information on how to calculate the GAI

WISC-IV General Ability Index (G.A.I.) Worksheet

WISC-IV Technical Report #4: General Ability Index

Correct me if I'm wrong, but I don't think there is much writing involved in the VCI and PRI subtests of the WISC-IV.

Thank you Cathy! If I did it right, we now qualify.

Uh-oh, Dottie. I'm revealing the secrets behind your powers...

Ooooo! How exciting

I second the magic powers. Dottie, you don't give yourself enough credit. To someone who isn't mathy - like me, you are the David Copperfield (or Harry Houdini) of GT calculations! (Sorry, I can't think of a famous female magician/illusionist).

Would someone be able to verify I calculated GAI correctly? I came up with GAI of 97 or 99.9%ile.

Vocabulary-18
Comprehension-14
Similarities-18

Block Design-14
Matrix Reasoning-18
Picture Concepts-15

Thanks. I'd appreciate it.

Here's the GAI Table for Canadian Norms in case anyone needs it.

hi all
i am glad to see they added it, but am still a bit baffled as to why they do not soften up the WPPSI requirements. The 150 is tough and there is no GAI. My DD5 got a 147 FSIQ which i am pretty sure is 99.9%tile and I am certain that if such a thing as GAI existed for WPPSI, her GAI would pass 150. Someone mentioned that the scores for young kids are less reliable somehow, so maybe that is the reason??
irene

Did these change? I'm curious because they really don't seem that high to me.

I am so with you. DS5 has both PIQ and FSIQ in the 99.9% but not the required 150. If there was a GAI for WPPSI, his would be more than 150. Dottie was kind enough to calculate GAI for DS7 (DYS, PIQ>=150) and his was over 150. DS5's GAI would be even higher. Stupid coding Extended scoring on WPPSI would be nice too.

At the very least it gives me a hope that if we wait for WISC then he has even better chance to get in.

Yay! Based on this DD8 should qualify. We were an eyelash hair away with the old standards, but make it with room to spare with the GAI. Problem is, our achievement testing is now out of date, but that is cheaper and easier than doing an IQ re-test.

Thanks for the info, made my day.

NCMom2 - only 1 set of data has to be w/in 2yrs.

We're thinking about applying DD for YS but I'm not sure these scores will do. Her FSIQ is only 135: She took the WISC-IV
VCI:
V = 18
C = 17
S = 18

PRI:
B = 14
M = 17
P = 17

PSI:
C = 9
S = 15

Please help. Do you think she qualifies?

Dottie, please work your "magic".

Thank you, Dottie. You are so fast. This is such a great group to come for info. Thank you all so much. My DD is 9. Which do you recommend, Explore, ACT or SAT and when/where can go to have her tested?

Her teacher recommended an IQ test so that's what we had done. She is in the GT classes now but she's starting to complain it's boring and this is just the first week! Should I have asked for an achievement test, too? I'm just now becoming more involved with my dd's education needs so I'm still a little behind. I've been to trusting in the school systems.

Thank you, Dottie. I'll call the psychologist who gave her the IQ test to see if she also gives achievement test. I am assuming that the WJ is the most recommended?

How 'bout for age 7?

& why? Or, can you direct me to a website that discusses the age-related preferences of one test over another?

Kinda moot at this point... considering HE'S RIGHT IN THE MIDDLE OF HIS TEST AT THIS VERY MOMENT AND I'M NOT DEALING WITH IT VERY WELL.... AND WHERE THE %$#!@ IS MY SCOTCH???

Whoa. Sorry.

Hugs to you, Dandy!

Actually, I'd love a brief overview of test type per age and processing skill (i.e. fast vs. slow) too!

I think ceiling issues are the biggest consideration with regard to age.

Different tests have different ceilings. If the test ceiling is too low, you don't get much information.

How recent does the WISC-IV need to be for a DYS application. With the GAI consideration I think DD would make the cut:
Similarities: 19
Vocabulary: 18
Comprehension: 18
Block Design: 16
Picture Concepts: 14
Matrix Reasoning: 12

These test scores are from 2005. We applied once before but she was not accepted. Since then she has continued to rank in the 99th percentile on state tests, explore tests etc. in the area of reading/English. Am I right that the GAI would meet the criteria? Do we need to have a new WISC IV done because they are so old?
Thanks.

Maybe not with the new achievement data. You can always send it in and see what they say...

I came up with GAI = 146. Is that what you calculated? What was the VCI? It must have been pretty high...

What is a VCI? Her Verbal IQ was 150, Perceptual 125, Working Memory 99 and Processing Speed 97 for a FSIQ of only 127.

VCI is the verbal composite. I think that's what you're calling Verbal IQ. I think that alone qualifies. Why not give them a call and see what else you would need to have a complete application?

Our WISC-IV report from a year ago has all subset scores along with FSIQ, but not GAI. Now that we can use GAI, can we still use that report, but without GAI calculated by the tester at the time?
Also a dumb question, how I can go about getting a WJ-III test? Thank you very much.

Dottie,
Wow, and thank you for coming to this question of mine (from another one of mine). I'd better get things together quick. Thanks for encouraging me to apply for DYS.
