Welcome!

You might want to remove any identifying information from your post. For example, kiddos are typically referred to as DS (Dear Son) and DD (Dear Daughter). List of acronyms here.

For a child on the Autism Spectrum, you may benefit by becoming familiar with wrightslaw, and their book From Emotions to Advocacy.

Lastly, you may wish to see if your child's test results meet the criteria to apply for Davidson's Young Scholars (DYS) program, although he may be a bit young. This could be something to keep in mind for future.
