This is the primary reason we are considering taking our son to do the WISC. He took the SB5 at 5 years, 5 months and while he scored in the gifted range, it doesn't match the level of gifted we see at home or his achievement testing. His SBV5 scores left him on that DYS bubble where he's not quite qualified but seems to be in real life.

Does anyone else have info on comparisons between the two tests?
