Not sure what you are asking... Quiz Bowl was a school activity for my kids. They were in a K-12 school, and by the time my last kid graduated (a top QB kid in our state), they had middle school and high school teams. But I think before they formed the middle school teams, the coach let 8th graders practice with the high school team.

Resources for kids who want to get better: ACE Quiz Bowl summer camps helped my kid a lot. She studied online a lot using resources like Sporcle. This is a great activity for gifted kids, it was my youngest's favorite high school activity. I hope your kid can find a team!
