Independent School League Sportsmanship Creed
The ISL values spirited and fair play as well as positive support for our players and teams. In order to ensure that our expected level of decorum continues each season and at each game, we ask that all members of the ISL community continually review their efforts to abide by the ideals of our league.

Athletic Competition in the ISL is guided by the following ideals:

Players shall at all times represent themselves and their school with honor, proper conduct and sportsmanship.

They shall understand that competitive rivalries are encouraged but that disrespect for opponents is unsportsmanlike and lessens the value of the rivalries.

They shall confine the competitiveness of the game to the field, and in particular behave properly on the sidelines and in the locker rooms both before and after games.

The Players
Players shall comply fully with the rulings of the officials. In no way, either by voice, action or gesture, shall they demonstrate their dissatisfaction with the decisions made. Players must never forget that they represent their school.

The Spectators
ISL schools do not tolerate any spectator, either student or adult, whose behavior is disrespectful toward players, officials, coaches or other spectators. Nor will they permit any type of spectator behavior that detracts from the proper conduct of the game or disadvantages a player or team. Some examples of unacceptable behavior during competition under guidelines of the ISL Heads' and Athletic Directors' Committee:

1. Use of profanity or displays of anger that draw attention away from the game

2. Booing or heckling an official's decisions, criticizing officials in any way, or displaying a temper with an official's call

3. Trashtalk or yells that antagonize opponents

4. Verbal abuse or intimidation tactics

5. Disrespectful or derogatory yells, chants, songs, gestures, signs, posters or banners

6. Any distracting activity such as yelling, waving arms, or feet-stomping during an opponent's free-throw attempts

7. Use of artificial noisemakers of any kind (legitimate pep-bands are encouraged.) These guidelines apply equally to players, coaches and fans. The ISL asks officials to apply these guidelines strictly, especially with regard to players and coaches.
