Definitely struggles with fine motor and writing is a disaster. Can do it when forced but hates it,
It's possible that the scores are reflecting your ds' ability to take in information or output information, rather than measuring the actual skill that the subtest is designed to measure. If you google WISC-IV + subtest name + description you should be able to find a specific description of each subtest. I found it really helpful to make a chart of subtest score vs type of output (and type of input) - you've mentioned that your ds struggles with fine motor and writing. See if there's a correlation between lower scores on timed subtests or subtests that require written output. You can do the same for reading vs verbal questions.
