NFHS's headquarters are located in White River State Park in Indianapolis, Indiana.

However, in states that have separate associations for public and non-public high schools, only the public-school bodies are full NFHS members.

[citation needed] The provincial associations of Canada are affiliate members of the NFHS.

The NFHS publishes rules books for each sport or activity, and most states adopt those rules wholly for state high school competition including the non member private school associations.

Since 1986, the Hall of Fame enshrinement ceremony has been the final event of the National Federation's annual summer meeting, which is held in late June and early July and attended by board members and executives of the state high school associations.
