In golf the distinction between amateurs and professionals is rigorously maintained. An amateur who plays for money even once usually loses his or her amateur status permanently and is banned from all amateur tournaments. A professional may not play in amateur tournaments. It is very difficult for a professional to regain his or her amateur status; simply agreeing not to take payment for a particular tournament is not enough.
Under the rules of golf and amateur status of the Royal and Ancient (Golf Club of St. Andrews), the maximum an amateur can win is £250. Under the rules of golf and amateur status of the USGA the maximum an amateur can win is $ 750. If an amateur accepts a prize of greater than this they forfeit their amateur status, and are therefore by definition a professional golfer.
Professional golfers are divided into two main groups, with a limited amount of overlap between them:
1. The great majority of professional golfers (at least 95%) make their living from teaching the game, running golf clubs and courses, and dealing in golf equipment. In American English the term golfpro refers to individuals involved in the service of other golfers. The senior professional golfer at a golf club is usually referred to as the golfclubprofessional, but at a large golf club or resort with several courses his job title is likely to be director of golf. If he or she has assistants who are registered professional golfers, they are known as assistant professionals. A golfer who concentrates wholly or nearly so on giving golf lessons is a teaching professional, golf instructor or golf coach. Most of these people will enter a few tournaments against their peers each year, and occasionally they may qualify to play in important tournaments with the other group of professional golfers mentioned below. Many golf club and teaching professionals working in the golf industry start as caddies or a general interest in the game, finding employment at golf courses and eventually moving on to certifications in their chosen profession. These programs include independent institutions and universities, and those that eventually lead to a Class A golf professional certification.
2. A much smaller but higher profile group of professional golfers earn a living from playing in golf tournaments, or aspire to do so. Their income comes from prize money and endorsements. These individuals are referred to as tournament pros, tour professionals, or in American English as pro golfers. See professional golf tours for further details.
In the developed world, the class distinction is now almost entirely irrelevant. Golf is affordable to a large portion of the population, and most golf professionals are from middle class backgrounds, often the same sort of backgrounds as the members of the golf clubs where they work or the people they teach the game, and educated to university level. Leading tournament golfers are very wealthy; upper class in the modern U.S. usage of the term. However in some developing countries, there is still a class distinction. Often golf is restricted to a much smaller and more elite section of society than is the case in countries like the U.S. and the UK. Professional golfers from these countries are quite often from poor backgrounds and start their careers as caddies, for example, Ángel Cabrera of Argentina, and Zhang Lian-wei who is the first significant tournament professional from the People’s Republic of China. In various countries, Professional Golfers’ Associations (PGAs) serve either or both of these categories of professionals. There are separate LPGAs (Ladies Professional Golf Associations) for women.
