rachsr, the Block design subtest is timed (most WISC subtests aren't, except Block Design and the Processing Speed subtests). So for a child with potentially relatively low processing speed (coding score) the Block Design score might also be impacted. OTOH that depends on why Coding is low - my dd's low score is Coding, but he hit the ceiling on Block Design. Coding requires a child to make marks with a pencil, Block Design requires the child to manipulate blocks to repeat a pattern - so in my ds' case, the low Coding score is due to a fine motor disability that impacts his ability to produce handwriting, but doesn't impact his ability to do other tasks with his hands such as moving blocks around.
Note: I'm relying on my memory re what the tests include - so my apologies if I've remembered them incorrectly in any way!
