The KBIT-2 is considered a screener, rather than a comprehensive instrument. There are differences of opinion in the professional community regarding how comprehensive the RIAS-2 is. (I assume this was a RIAS-2, and not the now-outdated RIAS.) Requesting a more complete assessment would not be unwarranted.
FWIW, there is some research suggesting that the RIAS nonverbal composite, in particular, diverges somewhat from some of the other standard instruments, with not particularly strong loading onto either general intelligence or nonverbal factors. Speed (if this is the RIAS-2) is probably not the main issue, as some attempt was made in the revision to reduce the impact of speed. It would not be shocking if a WISC-V came up with stronger Fluid Reasoning scores than the RIAS, given the student's KBIT-2 scores.
Thank you!
I did not see anything with the name of the test on it, so all I have is that I was told it was the RIAS. I assume it probably is the most updated version.
I mentioned the WISC to the tester (because I'd read that the GAI was a good option to use for students with processing speed issues). She said that since I had looked up info about that test she wouldn't be able to administer it, because "sometimes parents will try to prep their kids for the test." I clarified that the info I've looked up is about score reports and how they can be useful, not about what the test items are like. She insisted that my knowing ANYTHING about the test meant she wouldn't use it for my child. Is this standard practice? It seems like a parent should be able to educate herself on the options available for testing, to know what's out there and what kind of info the different options can provide.
Sorry for the tangent. Anyway, if I want the WISC, I will need to pay for it privately. If I go through the schools (and therefore this tester), I apparently shouldn't request a particular test and won't know what she'll choose.
What you said about the RIAS nonverbal is interesting and sheds a bit of light on things. I appreciate it!
