I'd be more worried about the "unleveling" if the leveling hadn't sounded like such a complete mess. No reading of nonfiction, or when they do, the text is modified among the different reading levels to become nonsensible?

"The New Colossus" does not appear to be at a 5th-grade lexile... high school would be my guess.

As long as the first-grader reading at a 6th-grade level has a G/T class available, the article isn't talking about our kids.
