The R&A



The R&A (or more formally, the R&A Trust Company (No. 1) Limited) is the collective name of a group of companies that together play a significant role within the game of golf. Historically, "the R&A" was a colloquial name for the Royal and Ancient Golf Club of St Andrews; in 2004, the club spun off its previous governance and tournament organisation roles into the current R&A group, with the club itself reverting to a private members-only club. The R&A is based in St Andrews in Scotland. The R&A is the sole owner of three subsidiary companies: R&A Rules Limited, R&A Championships Limited, and R&A Group Services Limited.

R&A Rules Limited is one of the governing bodies of golf worldwide, alongside the United States Golf Association (USGA). The USGA governs in the United States and Mexico, and the R&A in the rest of the world. They both share a single code for the Rules of Golf, Rules of Amateur Status, Equipment Standards and World Amateur Golf Rankings.

R&A Championships Limited organises The Open Championship, which is the world's oldest international men's major golf championship; the Women's British Open; the Senior Open Championship; plus the Walker Cup and Curtis Cup.

The Royal and Ancient Golf Club founded what is now the Official World Golf Ranking for male professionals in 1986, and the R&A introduced the World Amateur Golf Ranking for male amateurs in 2007. The R&A also owns and operates the R&A World Golf Museum.

Rules of golf
The R&A cooperates with the USGA in producing and regularly revising the "Rules of Golf", and the two bodies have issued the rules jointly since 1952. The "Rules of Golf" are revised on a four-year cycle. From 1990 for the first time a single common set of Rules applied throughout the world. The two bodies also collaborate on the corresponding rule interpretative work, "Decisions on the Rules of Golf", which is reviewed on a two-year cycle. Additionally, the R&A is involved in formulating technical specifications for golf equipment, which were first issued 1 January 2019.

Championships
The R&A organises 21 championships and international matches, which were previously organised by the Royal and Ancient Golf Club. After the Ladies' Golf Union, the former governing body for women's golf in Great Britain and Ireland, merged into The R&A in late 2016, The R&A took over organisation of all events formerly under the auspices of the LGU.
