Does anyone know if there is a substitute for block design on WISC V for kids who have challenges with motor skills? DS did the WISC IV a few years ago and his block design was much lower than the other two PRI scores (13 vs. 18-19). Other testing done the same day was below the first percentile for fine motor coordination. I don't know if he will be tested again, but we already know his block design score is affected by the motor skill issue (which the psych put in the report). What if we want to measure visual spatial ability without it being confounded by a fine motor problem?
