In MA, we use MCAS. He scored a perfect score on Math and ELA. So, the way I see it, compared to his peers his processing speed is not an issue. Compared to his other strengths, it stands out. But again, would this be an reason not to accelerate? I guess I am thinking I would rather advocate for him this way....should he encounter difficulty with the grade skip, I remind the teachers to allow some leeway given that he made an academic jump and may need time to adjust RATHER than explain to teachers in the next grade, please forgive my son's behavior, he's just under-challenged.
