USGA

The United States Golf Association (USGA) is the national governing body for the game of golf in the United States and plays a leading role in shaping the rules, equipment standards, and handicapping system used by players of all levels. The USGA traces its origins to 1894 when a group of American golf clubs formed to standardize the Rules of Golf and regulate national championships. It is a nonprofit organization headquartered in Far Hills, New Jersey, and operates in coordination with the R&A of St Andrews on worldwide rulemaking.

The USGA's core activities include maintaining the Rules of Golf in partnership with The R&A, administering the World Handicap System in the United States, and overseeing handicap calculations for golfers. It also conducts research through its Green Section on agronomy and course management, publishes course rating and slope data, and tests equipment to ensure conformity of clubs and golf balls with the Rules of Golf.

The organization stages a portfolio of national championships, including the U.S. Open, U.S. Women's Open, U.S. Senior Open, and U.S. Amateur, as well as various junior and women's events. It provides education and data resources to clubs, players, and fans, and maintains the USGA Museum and Library to preserve the game's history.

The USGA is funded through championships, memberships, charitable giving, and grants, and it operates as a nonprofit dedicated to preserving and advancing the game of golf in the United States. Its work is complemented by a network of regional and sectional associations that administer local competitions and handicapping practices.
