Most educators wouldn't dream of taking two such students as fifth graders, neither with literacy skills, and immediately stating that they were "the same" because they couldn't read and the rest of the (NT) class can... but that
is the error that they tend to make at the other end of distribution. If two first graders can both read
beyond grade level then naturally, they are "the same."
There is both a floor and a ceiling in that band-pass filter. Advocacy has done much to remove the floor (thankfully)-- but not as much about the ceiling.
I find that it helps me to keep my patience for longer to bear all of those things in mind.
