To extend this topic, my son (5y 5m) was recently tested with WPPSI-III and has the following scores:

Verbal:
Information - 15
Vocab - 16
Word Reasoning - 13
Total - 138

Performance:
Block Design - 18
Matrix Reasoning - 18
Picture Concepts - 17
Total - 148

Coding - 11

With a full of 138.

From my understanding of DYS, he would not qualify since neither his Verbal or Performance is above 150. Is that correct?

If so, I have a couple other questions (not to complain, just to understand). I thought his performance score was hitting the ceiling and he might have scored higher if the test allowed it. How can he hit the ceiling and not qualify?

Also, are the sub scores out of 18 or 19? From other posts in this group, I would say 19. But our psychologist (who ran the test) said 18. (actually she said he got every question right in the Block and Matrix tests.). I am a bit confused by if he got every question right how could it not be the highest number? Should I request the raw score? (It sounds like she was either confused when she told us the results or they calculated the results wrong. Or I am the one who is confused... Actually I am confused...)

Thanks in advance.
