I imagine because of the grade level material that your DS is doing it would seem awful silly to include him in this test. I imagine they just love to add his results to the pile of averages. If he has to take it is there a way for him to take it independantly so it doesn't take so long? We did this for my DD9. She took MEAP on her own in the special ed classroom, took about 2 hours total instead of the three days it took in the general classroom. Maybe they would be open to something like that, especially with his schedule, you could approach it as being less disruptive.
