My DYS son was a college-level reader last year at age 9. I stopped caring about his level right around then.

He's a voracious reader and likes everything from National Geographic to the Strange Story of Origami Yoda. He wants to read what the other kids in his class read (in addition to the many other books he reads). If his teacher told me to find more challenging work for him, I would just ignore it. He's a great reader. He loves reading. He reads anything and everything. And by the time he gets to college, he'll be an even better reader.
