About State Athletic Associations

Your state athletic association is the final word on eligibility, rules, and championships. They're the folks you call when a transfer student's paperwork is murky, when you need official tournament brackets, or when a rule interpretation could change a game outcome.

Most state associations are members of the National Federation of State High School Associations (NFHS), which coordinates rules and standards across the country.
