League Rules

The CISL Game Rules follow the current guidelines of the Iowa Soccer Association and US Youth Soccer, with a few minor modifications. These rules are designed to be age-appropriate, in terms of the size of the field, the number of players on the field, the length of the game, and sophistication. It is expected that every player will be given at least 50% playing time.  There is no limit to the number of substitutions that may be made in the game, save for referee's discretion about substitution at any given stoppage.

Sportsmanship:  (adapted from Alliance4All). All coaches, parents, and players are expected to remember the game is played for the fun and benefit of youth. Parents should act as a positive role model and never place the value of winning over the fun and safety of the players and by teaching their child to practice better sportsmanship. Parents should not criticize any player on the field nor the referee. The referee will typically be a young person just starting out and should be treated with respect and civility. It is never a good idea for coaches to discuss the referee’s performance nor rules at half-time or after the game. If you have concerns, please contact the league director cogilvie@iastate.edu  

At the end of the game, it is tradition to thank the referee and for the players to congratulate and thank one another. 

Important new rule for Spring 2016. Following the guidelines from US Youth Soccer, NO headers are allowed in practice nor games throughout CISL. Referees will award an indirect free kick for intentional headers.

About Jewelry

All jewelry must be removed for games. This includes earrings and watches, in addition to things like necklaces. This is a matter of safety. We cannot deny that "taping" of earrings occurs on occasion, but it is not officially allowed, is not as safe, and a referee is well within her/his rights to insist that earrings (whether just recently pierced or not!) come out for games.
