Thanks for the link! This is super-helpful in case we run into a teacher who insists she only read at her lexile level. Her teacher this year actually had the opposite reaction and told us at conferences that she gave DD a slightly lower "fake" lexile level for school (I think they are sometimes asked to search for books independently, it is not that the teacher won't allow her to read anything in her lexile), so that she would not accidentally run into material that was overly mature and inappropriate.
Fortunately, DD loves to read!
