Grand Slam tennis governance is built around a small, shared board that runs the four oldest international championships in the sport — the Australian Open, Roland-Garros, Wimbledon, and the US Open. The board comprises the four Grand Slam Chairs supported by the CEOs of each tournament, and it operates as the decision-making body for sporting matters common to all four events. Its decisions are reflected in the annual Grand Slam Rule Book, published by the International Tennis Federation.
The structure exists because the four Slams are owned and run by their respective national federations or clubs — Tennis Australia, the French Tennis Federation, the All England Lawn Tennis Club, and the United States Tennis Association — yet they need to agree on rules that travel with the players. Without a shared rule book, the same player could face different code-of-conduct standards in Melbourne, Paris, London, and New York.
The Shared Board
Grand Slam Tennis, as the board is formally known, is responsible for reviewing and deciding on sporting competition matters across the four events. Its scope includes:
- Grand Slam Tournament Rules and Regulations
- The Code of Conduct for players, coaches, and support teams
- Officiating standards and umpire certification
- Relationships with governing bodies — the ITF, ATP, WTA — and third parties such as broadcasters and data providers
- The Grand Slam Player Development Programme and its grants
The four Slam Chairs hold the votes; the CEOs provide operational input. Decisions taken collectively are then implemented at each tournament site through the local referee and supervisor structure.
What the Board Does Not Decide
Several important areas sit outside the board’s remit. Each tournament still sets its own prize money, ticketing, broadcast contracts, and partnership deals. The court surface, ball brand, and scheduling format remain with the host federation. And the broader regulatory architecture of professional tennis — anti-doping (ITIA), competition integrity, ranking systems — sits with the ITF, ATP, WTA, and ITIA.
So Grand Slam Tennis is not the regulator of the sport. It is a coordination board for the four events, working within a wider tennis governance system.
The Grand Slam Rule Book
The Grand Slam Rule Book is the single document that codifies the board’s decisions. It covers entry, draw, seeding, scheduling, on-court conduct, equipment, dress, and prize money structure. The ITF publishes the rule book each year on behalf of Grand Slam Tennis.
Entries and Wild Cards
Entries into a Grand Slam main draw fall into three buckets — direct acceptances based on ranking, qualifiers, and wild cards. Wild cards are entries granted at the discretion of the host tournament. They are included in the draw and cannot be added after the draw is made except under specifically defined sections of the rule book.
Each Slam has a fixed allocation of wild cards in singles and doubles, and reciprocal wild-card agreements between the Slams (for example, between the Australian Open and the French Open) give selected players from one host nation a pathway into another Slam’s main draw.
Code of Conduct
The Code of Conduct sets out offences, penalties, and the schedule of fines for behaviour during a match — audible obscenity, racket abuse, ball abuse, coaching, unsportsmanlike conduct, and visible obscenity. Penalties escalate from warnings to point and game penalties, and finally to default for repeated or serious offences. The chair umpire enforces in-match decisions, while the referee handles match-day appeals.
Age Eligibility
Age eligibility is one of the most distinctive features of professional tennis. The Grand Slam Rule Book aligns with the wider ITF Age Eligibility Rule. Players must be at least 16 by the start of the tournament to compete in any Grand Slam — main draw, qualifying, or junior wild-card entry into the senior draw. Fourteen-year-olds may not participate in Grand Slams.
Younger players have separate pathways. The ITF Junior Circuit accepts entries from age 13. The ITF and tour circuits allow restricted numbers of professional tournaments for players aged 14 and 15, but those events do not include the four Slams. The intent of the rule is to protect adolescent players from year-round high-intensity competition, with the American Academy of Pediatrics finding higher overuse-injury rates among young athletes who play through the year in single sports.
Player Development Programme
Beyond rule-making, Grand Slam Tennis runs a Player Development Programme that funds grants and pathway support for younger professionals. The programme is administered jointly by the four Slams and is publicly profiled each season around Roland-Garros.
How the Four Slams Differ
While the rule book unifies sporting matters, the four Slams remain distinct in surface, season, and culture. The Australian Open opens the year on hard courts at Melbourne Park. Roland-Garros follows on clay in late May. Wimbledon is played on grass in summer. The US Open closes the calendar on hard courts in New York. The shared board ensures the rules of play and conduct are consistent across these very different conditions.
Why Centralised Governance Matters
The case for shared governance is practical. The same top players appear at all four events, often with the same coaches and support staff. Inconsistent rules — on coaching, on heat policy, on time between points, on tie-break formats at fifth or third sets — would be unworkable for the tour. The board’s job is to keep the rule book aligned even when the host federations differ in approach.

What does the Grand Slam board decide?
The board reviews and decides on tournament rules and regulations, the code of conduct, officiating standards, and relationships with governing bodies and third parties.
Are 14-year-olds allowed to play Grand Slams?
No. Players must be at least 16 by the start of the tournament. Fourteen-year-olds are not permitted to compete in Grand Slams under the Age Eligibility Rule.
What is the Grand Slam Rule Book?
The Grand Slam Rule Book is the annual document published by the ITF that codifies the board’s decisions on rules, conduct, entries, and prize money structure.
How are wild cards allocated at a Grand Slam?
