My DYS took the SB-5 at 4 years 9 months old and the WISC-IV at 8 years 9 months old and the FSIQ was the same for both tests. He is a pretty mathy kid.
It was interesting to be able to see the different areas that each test tested. On the SB-5 the Quantative Reasoning was the highest subtest along with Working Memory. The WISC-IV show strengths in Perceptual Reasoning and Working Memory.
We also used the same tester for both tests so I am fairly certain that we have a good idea of his IQ.
In my opinion having both tests done might give you a more accurate assessment. However I do feel that the tester could play a role as well.
