I don't know if this will help, but when my dd took the wppsi at age 3y5m, she was given only 3 of the 4 subtests.

Receptive Vocabulary - 18
Information - 19
Picture Naming - 18

That gave her a verbal iq of 147. Not quite DYS numbers. That's one of the reasons we're thinking of retesting her at 6yo on the WISC.
