Have you talked with the school about the possibility of him taking some end-of-3rd tests (like math)? Sometimes this can get teachers looking directly at their own curricula with which they are very familiar and seeing how your DS's knowledge compares with what they would be teaching him.
Also, schools can vary considerably in students' general achievement levels, so while it's very helpful to know the national percentile scores, it can also be helpful to know how your DS's scores (like his MAP scores) compare to other students in his grade and in the grades above him. Perhaps it would be possible to get this information from the school? Maybe at least find out averages for each grade level and/or whether your DS might have some other students in his grade who are at a level similar to his?
Another possibility, if the school is resistant to subject or grade acceleration, might be to allow your DS to pre-test units of study (like, again, math) and if he meets some benchmark, allow him to work on some materials you send from home or on some other materials they provide.
