Do you mind sharing what your son's age was when you received this recommendation?
DS was 5. To give some background, DD was already a DYS and DS had taken the WJ, with very high scores. The tester therefore opined that the WPPSI did not have very high ceilings for 5-year-olds and that it would be better to wait until he was 6 so that he could instead be tested on the WISC. I was hoping to just test him once, so in retrospect, this was a good recommendation. Also, the WISC (the IV was all that was available at the time) had extended norms, which he ended up needing.
