Thanks for your suggestions, 13umm. We've had the discussions about the computer as a tool, but I will try your other ideas. Since my post, I also had him take one of the practice online test sections and video record him over his shoulder. I then reviewed it with him to point out where he did things that were not related to answering the test questions. I thought this third person point-of-view may be helpful, but he hasn't taken any further tests yet to see if it made a difference, and we haven't scored the test so he can compare his activity to his results.
