We found Lexile useless because DD reads only for pleasure and what she prefers to read is about 400-500 points below her range. probably like what most of us would do. When we tried some titles out on her that were in her upper range, she got spooked or simply had no interest.

At this point a high Lexile score seems to be a hazard because it makes her teachers think she should be reading things she shouldn't. This happened in 2nd grade when her teacher let her read anything in the library and she got spooked. This year we warned her 3rd grade teacher in advance in case DD scores high on reading tests again.

Speaking of which, I've heard other parents report their child's Lexile score changing dramatically, like dropping several hundred points from the previous year, etc. I'm skeptical of how accurate a measure it really is.
