re: Anyone have kids at a school with a "house" concept?

This is actually pretty badass, I imagine.

Adds competition to school, but the fact it's a team competition likely makes kids more apt to participate and push themselves to excel so as to not let down their teams. Having the older kids available to provide mentorship gives kids who may have an unimpressive home life the belief that someone cares.

Good stuff. I love innovative approaches like this.
