The New Hampshire Interscholastic Athletic Association (NHIAA) is the governing body for sports competitions among all public and some private high schools in the U.S. state of New Hampshire. It is a member of the National Federation of State High School Associations.
Classifications
Schools competing under the NHIAA are grouped into four divisions (classification thresholds as of July 1, 2025):
Division I: over 900 students Division II: 501-899 students Division III: 281-500 students Division IV: up to 280 students
Schools are reclassified every two years. The classification thresholds are periodically adjusted so as to result in an approximately equal number of teams in each class. Schools may petition the NHIAA to play in a class higher than that in which they would otherwise be placed.
For most multi-division sports (e.g. football or ice hockey), competition is organized into divisions based on enrollment thresholds established by the NHIAA committee governing the individual sport (which can very based on the number of participating schools in a sport).
Classifications for the 2024–2025 and 2025–2026 seasons are as follows:
Division I (formerly Class L): 20 schools
Division II (formerly Class I): 20 schools
Division III (formerly Class M): 23 schools
Division IV (formerly Class S): 26 schools
