napanangka, I noticed in a previous post you mentioned your ds was given the SB-V previously. I am not familiar enough with the SB-V to know how to examine the scores, but you might want to have someone look at the previous testing to see if there is a subtest that correlates to BD and coding or relies on fine motor, and look for a similar pattern there. If you see a pattern of low scores related to fine motor on the SB-V, that would be another reason to not assume that perfectionism caused the low scores on the WPPSI.
