The Idaho High School Activities Association (IHSAA) oversees high school athletics and activities in the U.S. state of Idaho. Idaho high schools are classified in six categories, based on enrollment, for league competition and state playoffs and championships. The IHSAA recognizes twenty specific sports and activities.[1]
Schools primarily compete within their own classification for regular season play, but are allowed to play other schools one classification above or below them in most sports.[2]
Historic classifications
IHSAA classifications are based on four-year enrollments (grades 9–12).[3]
The classifications for the state's 171 high schools for 2026–28 are:[3]
