Hi mom.org ~ You mentioned that your son has a high IQ but just how high? Could not being challenged enough be a possibile cause of your son's low executive functioning skills? I mention this because my son (also visual spatial) had terrible ef skills until he got grade skipped. I'm not sure if it was him just maturing or what...BUT the grade skip sure seems to have wiped away these past ef problems! Hugs and good luck! smile
