Yeah, I guess it would be pointless to tailor tests for children like that since they are such a minority. I have the same problem when we go to the library to get books. I can't find any books that would challenge him to read the words where he could still comprehend the topic. The topics of books for 6th graders just don't really appeal to him, and often aren't appropriate for a child that just turned 4. Although non-fiction is usually okay for him.
