Our school has proposed the use of the Lexile framework as our leveling system. I don't know a great deal about it. I'm not sure how I feel, negative or positive. My entire library is leveled by AR. A couple of my co-workers are through the roof not happy . Being the book nerd that I am, I'm ready to jump right over and add the Lexile levels to my books. Who out there uses this system and what do you think about it??
