As 30% of the WISC-IV measures abstract verbal reasoning, compared to 10% of the SB5, the WISC-IV is likely to find more highly verbal children. As 20% of the SB5 measures mathematically gifted children, compared to 0 � 10% of the WISC-IV (depending if Arithmetic, an optional test, is administered), the SB5 is likely to find more mathematically gifted children. While 20% of each test is devoted to the measurement of visual-spatial abilities, there may be more visual-spatial content in the SB5, so it may be preferable for locating spatially gifted children.
