If your son's' IQ is in the 140s, even with average processing speed, he is probably ready for input 2-3 grade levels up (and possibly higher), particularly in the areas where he scored at the 99th percentile. I'm basing this on my experience with my son who has a similar profile and was homeschooled until this past spring.
