DD tested on the SB5 and I wouldn't say she is particularly mathy. She did get a DYS qualifying score. Her FSIQ is a bit lower then her WJ ACh and her RIAS, but I would say it is valid. One thing to ask is if you think your DC may ceiling out in a few areas on the SB5 ask the tester in advance if they have the manual to calculate the EXIQ. I found that many psychs and some even recommended on Hoagies didn't think the SB5 had the ability to calculate extended norms and none had the manual. I think most psychs who administer the SB5 don't administer it as often as the WISC, and when they do use the SB5 they don't come across those who qualify for extended norm calculation.
On a side note, I was told multiple times the SB5 is coming to the end of its life and a new version should be out within a year or so.
