Thanks, Zen. Yes, I do not feel great about the SB5 because of what I have heard about it (similar to what you have pointed out here), but also because testers in my area seem to use it only rarely (which I am not very comfortable with).
I've honestly not heard of anyone around here taking any of the other tests listed - the WISC seems to be some sort of "gold standard" here. The WISC would definitely be most useful in the long run here (for whatever purposes going forward), because it seems well-recognized and respected.
Thanks, KADmom and syoblrig.
Thanks to everyone here for your feedback! Much appreciated!!!
