My older daughter has just had yet another round of testing, looking at Aspergers. She came out flat and exhausted and came down with a pretty impressive fever the next day. Which always gives you a warm fuzzy feeling about spending more money on an IQ test in a child with clear unpredictability on the best of days... She's not remotely HG, we know that, but in some respects this is her worst result, which is unfortunate as it will be her last IQ test and the one we need to use for highschool applications etc.

My question is - with a 30 point / 61% spread between VCI and WMI should the FSIQ have been calculated? I thought this fell into the "could not be calculated" range of difference?

We don't have any subtest scores just the indexes:

VCI 124
PRI 123
PSI 112
WMI 94
FSIQ 120

The GAI is still not going to fall into the gifted range, I think it would be 126 or 127? Is there any point in asking for the GAI to be calculated when she's not going to pass 130 anyway?

I don't know whether to leave it as is or ask for the FSIQ to be removed, and whether to ask for the GAI or not.

I would ask for the GAI to be calculated. I'd also ask for the subtest scores. As for the FSIQ, technically, it should not be reported.

Thanks for your thoughts! This guy is very old school and following the guidelines that say parents should never see the subtest scores. I am lucky he didn't give me only percentiles. We were using him for the ASD assesment, he wanted to do a fresh IQ test as part of the process and we agreed. I now regret that.... It's a long and complicated tale as to why we used him, he's very well respected and very good in many ways, I just wouldn't have chosen him for IQ testing if that was all we wanted. It's a pain to have a 1yr old IQ test that gives her a FSIQ of 131 that we now can't use (done with a tester she liked and came out buzzing from, and on a day she wasn't sick).

I wouldn't pay this guy until he gives you a *full* report, including subtest scores, because honestly, that's where the information is.

Maybe I'm missing something, but why can't you use the older test?

I believe the regulations of the registering body in Australia actually prohibited or strongly recommend against providing subtest scores. I would like them because I like numbers and it would be nice to do a direct comparison with her last WISC (which also did not come with subtest scores and it was extremely difficult to get them). But really I have all the data I need on this child, I already know that she's going to have had significant scatter with in the sub tests...

Loc: Sparta, apparently
If the same tests were given a year apart, wouldn't the older one be more valid? I thought there was supposed to be a 2 year spacing.

Wow, I'm glad I don't live in Australia. Why on earth would they prohibit providing subtest scores? That's crazy.

She last did the WISC three years ago, she did the sb5 one year ago, we expected that to be her last test. I do find it annoying that Australian psychologists are so anti providing parents with all the data. Some are more flexible than others.
