How accurate is this cognitive assessment for ASD/dyspraxic type issues. Just got DS's back from new LA and he's at 1 centile for several things. (more than half of the categories tested) Previous assessments have always shown a VERY spikey profile with 5th centile for some audio related stuff being his lowest score & 97 being the highest, but most stuff being over 50th centile.
He's not been assessed for several years, but I didn't expect his scores to vary THAT much from previous ones. Is it common for scores to vary so significantly over time? Part of me is wondering if the wrong table was inserted into the report, but tbh I know nothing about these things.
