I can not help but feel a little put off by a parent telling you how to teach their child. You are the professional. I have had incredibly intelligent children in my classes. There are ALWAYS areas they need work on regardless of intelligence or reading ability.
Translation: "I will poke and pry at this child until I find something they're not perfect at, and then I will torture the child over that one thing so that I don't have to do any acceleration. And so that I don't have to admit to the parent that I'm not the Overlord of Pedagogy."
