Do you know what the alternative would be to coding on the WISC V? I might have to take DS to be tested and don't really think that subtest makes a lot of sense for him, given his low tone and DCD. He doesn't even hold a pencil correctly. Also block design requires motor speed and I don't see him being particular speedy, even though he has very good visual spatial ability. Kind of like the pegboard (the test involves putting pegs in holes and it's timed)--he scored well under the 1st percentile. Meanwhile he was above the 99th percentile for the PRI tests that didn't involve motor skills. I can see how those subtests make sense if you are TRYING to find a disability, but the school districts don't understand that when they're just plugging numbers into their computer and rank ordering scores for g/t services.
