I actually thought that the "fake" lexile range was a bit odd at first, but when the teacher explained the reasoning behind it - she really was thinking "like a mom" - and I actually appreciate that she cared about DD, who turned 8 this summer, stumbling across sex and violence when looking for books on her own.
We go to the library OFTEN and USE our library, so DD reads - fiction, nonfiction, in-lexile, out-of-lexile, including above-lexile (we realize it is just a guide) - no problems there! She is the kid I need to tell, "STOP READING AND GO TO SLEEP!" But it is a great problem to have, really.
My bigger problem is tracking her progress - and this is why the MAP test interests me. I seems like at least "a" (and certainly not a sole) measure for progress above grade-level. When she brings home 100% grades on schoolwork that looks easy for her, I am not necessarily convinced she is making progress in learning. I need to find more/better ways to ensure she continues learning in various subjects.
I do appreciate the suggestions and concern - this place is great! I love the idea about keeping track of the books - that is easy to overlook when you have a "book eater."

Thanks so much!!!
Thank you also for the suggestions about FERPA. I am familiar with it, but I hate even bringing up the law, if I can accomplish my goals with gentler persuasion. I want to avoid making anyone adversarial, if possible. I am very happy to have it in my back pocket, though.
