A national standard rule book for high school football is maintained by the National Federation of State High School Associations. This organization publishes an official rulebook that can be purchased from its website.
The rules committee of The National Federation of State High School Associations meets annually to evaluate the effectiveness of any rules changes in the past year and consider rule changes for the upcoming year. Rule changes are evaluated on their potential to maintain or enhance fair play, sportsmanship, minimization of risk to athletes, traditions of the sport, and a balance between offense and defense.
In addition to the actual rules, the National Federation of State High School Associations also publishes rule interpretations and points of emphasis, as well as guidelines for officiating games, all of which can be found on its website.
