I would avoid talking "boredom" with the school though. It is really just a symptom. It might be an easier conversation about seeing needs/opportunities to provide greater challenge. The desire for your child to receive a year of academic growth for a year's time.

Reforming GT ED does address the model student who isn't demanding but deserving. Also, I believe Sylvia Rimm's (and somebody else) textbook titled Gifted and Talented does - but I'll look that up and see if I can just find the passage (I just had it out).
