Whoa! Those are HUGE IQ scores!

My son is also dyslexic -- tests in the pg range (if you count the DYS cut off as pg -- not even close to your son!)

We remediated with intensive tutoring through Lindamood Bell. I felt lucky because they seemed to "get" him and started him at the right level. But they were very clear that they don't usually see kids like my son -- and your kid is about 3 standard deviations above my son. I think part of what worked for us at LMB was the individual staff. I think that you have a really unusual kid. Is homeschooling an option?
