...to know if this is something I want to pursue at all).
I do realize that my prior reply might have come across as abrupt and apologize if so. I wasn't intending to insinuate that you were intending to prep your dc.
This quote from your post, though, had me thinking -- why
are you pursuing testing and why the RIAS? I think that, if you can answer those questions, you'd have the answer you are seeking as to whether to pursue the testing. If your ds needs the scores for some program, is this the only test they take? Is there a reason why you're not going with a more well known IQ test? None of that is to say that the RIAS isn't a good choice, but the WISC or SB might be better known and accepted.
eta: now that I've bothered to look at your prior posts
, I do see your motivation in testing. It is hard when we feel like our dc can do more than they are and I understand not wanting a child to fail to progress adequately due to lack of challenge. I guess, in your spot, I'd be inclined to just go with the SB-V because it is better known and you can do it now rather than waiting until he is six like you would have to for the WISC. I'd also see what you can do in terms of heading off similar problems to what you had with the WPPSI. Talk to the new psych ahead of time, explain what went wrong with the WPPSI and make sure that she has a plan to engage him and not let him see what she's circling in terms of scoring.
