As far as the rules go, the National Federation (NFHS) makes high school rules. Most of them, hwevoer, are the same as the FIFA Laws of the Game. That book can be downloaded for free at. There are a few differences in the NFHS rules. A few (not a complete list) differences are: 1. NFHS games have no stoppage time. The referee stops the clock for certain events, but when the clock hits zero the half must end.2. In NFHS, a player who is sent off due to a second yellow card can be replaced.3. An NFHS throw in which does not enter the field is not retaken. The other team gets the throw.As far as postions go, this is a cut-and-paste of an answer I gave a few days ago:The only position required under the rules is a goalkeeper. The other positions developed over the decades. Other than the goalkeeper, common positions include (but are not limited to):Forwards: The main job of the forwards is to score goals. In the old days most teams used 3 forwards. 2 were wingers, and played near the side of the field. The other was the center forward, who played basically between the wingers. Forwards are often called strikers nowadays.Midfielders: Midfielders (formerly called halfbacks) play between the forwards and the defenders They have both attacking and defensive responsibilities. Midfielders often do the most running on the team.Defenders (formerly called fullbacks): They primarily have defensive responsibilities. They try to prevent the opponents from taking a shot on goal. Team formations go from back to front. For example, if your coach wants your team to play a 4-3-3 it means your team will have 4 defenders, 3 midfielders, and 3 forwards.
