NFHS High School Basketball Rules

high school basketball rules

Get the latest official high school basketball rules, updates, and interpretations. Each year, the National Federation of State High School Associations publishes an updated rule book for boys and girls varsity basketball to ensure consistent standards for competition across the U.S.  

As the recognized national authority on interscholastic athletic programs for all 50 states and the district of Columbia, the NFHS also provides a variety of publications and resources including high school basketball regulations organized by topic, casebooks with rules interpretations, and handbooks with simplified illustrated rules.

In addition to the NFHS, each state has its own interscholastic athletic association that governs basketball competition within the state. These organizations write their own handbooks with rules for competition specific to their school districts statewide. Follow the links below to find the high school basketball rules for your particular state.
