Sportsmanship Guidelines

The development of sportsmanship is an important part of growing up. To become contributing, competent, caring, capable adults, youth must develop sportsmanship. It’s important for people to be fair and generous competitors, good losers, and graceful winners. All participants in 4-H, County Fair, and other youth programs are expected to demonstrate the elements of sportsmanship before, during, and after their participation.
