Agreed!

Two thoughts:

1) Beware of what a school might offer to challenge your child: extra work, busywork, solitary work, tutoring other students, requirements to teach himself advanced material, more stringent grading requirements, etc, as described in this list of buzzwords.

Appropriate challenge is instruction at the child's zone of proximal development (ZPD), amongst academic/intellectual peers.

2) In the advocacy tips, parents are cautioned not to use the word "bored" when talking with teachers.
