Ditto what Aculady said. I've heard even really bright GT teachers make comments like that. I'm sure that there are kids who sound out and "read" stuff that they don't comprehend, but that doesn't mean that all kids who are way above grade level on reading aren't comprehending and her MAPs scores definitely support the belief that she is comprehending what she reads.
Some of the std stuff that teachers suggest or believe just doesn't apply to HG kids. For instance, I recall numerous teachers in the early grades for both of my dds saying that you should have kids read books that are a little easy for them to build confidence and not give them books that are too hard -- that they'd progress more quickly if they weren't overwhelmed with too challenging material.
That may be true for most kids but it wasn't with my oldest. We routinely read books that were right at the top of her lexile and sometimes beyond and her reading would always jump when she was stretched like that.
