They do adjust the required ACT scores for a 6th grader even though it's not published. I think because many of the testing centers won't let you take the ACT until 7th grade. I asked once before applying and they told me that much. I didn't ask for specifics since we met the 7th grade requirements but if you aren't sure, you could send them an e-mail and see if they will send you the 6th grade numbers. If they do you could better determine if he is a candidate. Either way I think he's pretty close so I would be hunting for really strong portfolio items because I think that can help sway things when someone is on the line.
