I don't know what the PDMS is but DS scored in the 65th percentile on the Beery VMI a couple years ago and he just did it again, but only the motor coordination section, and was at .02 percentile. He also did the BOT and had subtest scores ranging from around the 5th percentile to 30th or 40th percentile (the motor coordination section of the Beery should have been very similar to one of the subtests of the BOT, and there is a big difference between .02 percentile and 5th percentile!). I'm not sure what to make of these tests but I do know it's better to look at individual subtest scores than whole test composites. Whenever DS does motor skills testing there are always really large gaps from subtest to subtest and his overall score isn't necessarily that low. He also has dyspraxia (and probably dysgraphia). Hope this helps.
