My 7 year old has an IQ of 135, although the NVFR is 99.9% on the SB5. DC is working a few years ahead and I'm asking for a two year skip. Is this too much considering the IQ scores?
A lot would depend on the actual scatter within the IQ test as well as the quality of your DS' school and rather he is old/young for grade. Based on the limited information in your post, I would hesitate to skip two years. If such high NVFR only results in a full scale IQ of 135, then it means that either his verbal IQ and/or processing speed is only high average or lower. Schools typically emphasize verbal skills and require reasonable processing speed. Based on the posted age, I am assuming that you want your DS to skip 2nd and 3rd grade and jump to 4th grade. The writing and executive demands in 4th grade are significantly higher in most decent brick and mortar schools.
I'm quoting the above to draw more attention to it. This is what I'm experiencing with my son. He has FSIQ of 132 (GAI 141). His score is brought down by slow processing speed and working memory. However, he has ADHD dx so we have some wiggle room for academic accommodations.
He is in virtual charter school that offers a blended option, so I can chose his environment for each individual subject. I choose his grade level for each subject. I can also chose his level of accommodation for each subject. I did subject acceleration in grade 2 and 3. He skipped from public elementary school 1st grade to charter school 4th/5th grade for his 2nd grade year. 3rd grade year he did grade 6 with higher level supplements.
He is 9 now, would be entering 4th grade. We did formal grade skip acceleration to 7th grade. He'll be taking 2 middle school classes, 2 high school classes, and 1 will be either high school or college - awaiting instructor approval. However, he will have accommodations available for ADHD in each class. The high school classes can be done at half-pace, meaning one semester is spread over two semesters. 2 of his classes wil have no required writing, no written homework. If he gets approved for the college class, he'll have accommodation for private test room, time-and-a-half on tests, extended time on assignments, and a note-taker (that's me).
He is intellectually capable of the material, but his processing speed, working memory, and slow writing would prevent him from participating in these classes if not for the ADHD dx and parent involvement. My role is to be aware of his asynchronies and abilities so I know when to push him and when to stop, break it down, and teach a lagging skill. My role is to teach organizational skills. ("Organizational Skills Training for Kids with ADHD" <-- book is worth its weight in gold!)
For reference, his processing speed when optimally medicated is 50th percentile. Unmedicated it's approx 20th percentile.
For your son, I would recommend preparing him for a skip over a couple of years. The difference between grade 3 to 4 is significant and the difference between 5 to 6 is often troublesome. Subject acceleration might give you an opportunity to teach him the study skills separate from social skills and academic organization skills. When he can keep up with the non-intellectual / executive demand of higher level work you'll be better able to make a grade-skip decision in confidence.
