The reading level question is an interesting one. I am really not sure of DD's reading level, or even that such a thing can be definitively known--but her fluency is 190 WCPM and that is about 50th percentile for 8th graders. (Grade level expectation was 53.) Her guided reading level, according to them, is Q--4th grade. All of that seems to suggest she may benefit from differentiated reading instruction, though I am not sure how uncommon she is for her particular class/school.
