Eh.
What Val said.
I gave up using this sort of
tool when Lexile recommendations for my 7yo included
Tess of the D'Urbervilles and
Madame Bovary.
Sure,
Oliver Twist might have been fine for my particular 7yo (and was, in fact, fine
for HER), but I had to draw the line at Flaubert.
It was then that I realized that such tools are probably entirely UN-helpful for parents or teachers of children who are fluent or advanced readers.
Which begs the question; why are such children forced to participate in evaluations intended to provide this kind of feedback, hmm? I digress.
