What Kids are Reading

Renaissance Learning just published a new report titled What Kids Are Reading: The Book-Reading Habits of Students in American Schools. This report claims to be the first comprehensive report to provide detailed information about the books school children are reading. Based on my untrained review of the results, it looks to me like kids are mostly reading books they've been assigned to read (and Harry Potter). I don't see how this report is very useful. Change the curriculum, and you'll change the results. What I'd really like to see is what kids are reading that hasn't been assigned.
