AR...I like it but...How do you handle teachers who pick up their classes and inspect their book choices to make sure that they are AR. We have a AR obsession...My compromise is that they can check out two-one needs to be AR. An easy thing for me to handle ar reading ranges is to a classroom set of index cards with students name, reading level and teacher. I spread them out before checkout and students turn them in to circulation desk after checking out. We keep them in classroom sets banded so they aren't lost. that seems to help manage the AR level quest esp. for the younger ones.
