The Association of Tennis Professionals, better known as the ATP, is the organization behind much of men’s professional tennis. It runs the ATP Tour and Challenger Tour, publishes the ATP rankings and works with players and tournament organizers on the sport’s professional circuit.
The ATP is not in charge of every tennis event or every rule. Grand Slam tournaments are run separately, while the International Tennis Federation (ITF) oversees areas such as the rules of tennis and team competitions. Knowing where the ATP fits makes the tour calendar, rankings and tournament levels easier to follow.
What is the Association of Tennis Professionals?
The Association of Tennis Professionals was founded in 1972 by people involved in the men’s game, including players and tennis leaders. Its purpose was to give professional players a stronger collective voice and help organize the sport. Cliff Drysdale, one of its founders, became its first president.
Today, the ATP is a professional tennis organization built around both players and tournaments. It operates the ATP Tour and ATP Challenger Tour, sets the structure for those events and represents the interests of the people involved in them. The ATP Tour includes the main weekly circuit, while the Challenger Tour gives players another level of competition and a path toward higher-ranked events.
What does the ATP do?
The ATP’s work is visible in the weekly tennis schedule, but it also shapes how players enter tournaments and how fans follow the season.
- Runs professional tours: The ATP manages the ATP Tour and ATP Challenger Tour calendars and competition structures.
- Maintains men’s rankings: It publishes the ATP Rankings and the year-long ATP Race standings.
- Sets tournament standards: ATP rules cover matters such as event operations, player commitments and tour competition.
- Represents players and tournaments: Player and tournament representatives have a role in ATP leadership and decision-making.
- Shares results and information: The ATP provides schedules, draws, scores, statistics and player information through its platforms.
These responsibilities make the ATP central to the men’s regular tour, but they do not make it the sole authority over professional tennis. For instance, Wimbledon and the US Open are Grand Slam events organized separately from the ATP Tour. They award ATP ranking points, but the ATP does not run them.
How the ATP ranking system works
The ATP Rankings are based on a rolling 52-week period. A player earns points by reaching certain rounds at eligible tournaments. Bigger events generally offer more points, and a deep run is worth more than an early loss. As results from the previous year drop out of the calculation, a player needs new results to defend or improve that ranking.
Rankings matter beyond bragging rights. They help determine entry into many tournaments and can influence seeding, which affects how players are placed in a draw. A player ranked inside the top 10, for example, is more likely to receive direct entry and a favorable seed than a player outside the main draw cutoff.
The ATP Race is different. It tracks points earned during the current calendar year and gives fans a running view of the season’s leading players as they compete for places at the ATP Finals. The rankings look back across 52 weeks; the Race starts fresh each season.
| System | What it tracks | Why it matters |
|---|---|---|
| ATP Rankings | Results over the previous 52 weeks | Tournament entry and seeding |
| ATP Race | Points earned during the current calendar year | Season standings and qualification picture for the ATP Finals |
This distinction can explain why a player might be high in the Race but still sit lower in the official rankings: the Race reflects only the current season, while the rankings also include results from the latter part of the previous year.
ATP tournament levels
Not all ATP events offer the same ranking points or draw size. The main tour includes several categories, while Challenger events give rising players and comeback candidates a chance to build ranking points through regular match play.
| Competition level | Role in the season | Typical importance |
|---|---|---|
| ATP Masters 1000 | Major events on the regular tour calendar | High ranking-point value and strong fields |
| ATP 500 | Important tour events below Masters level | Valuable points and competitive draws |
| ATP 250 | Regular tour events around the world | Opportunities to win a title and build a ranking |
| ATP Challenger Tour | Development and ranking pathway | Key match experience for players moving up the levels |
| ATP Finals | Season-ending event for leading qualifiers | A chance to finish the year with a major title |
The number in an event’s name refers to the ranking points available to the singles champion. It is a useful guide to the tournament’s place in the tour, though draw sizes, format and qualification details can vary.
How the ATP differs from the ITF and Grand Slams
Professional tennis has several organizations with different jobs. The ATP runs the men’s regular tours, while the ITF has broader responsibilities, including the rules of tennis and international team competitions. The four Grand Slams—the Australian Open, Roland-Garros, Wimbledon and the US Open—are independently organized tournaments. They are not ATP Tour events, even though their results count toward the ATP Rankings.
| Organization or event | Main role |
|---|---|
| ATP | Operates the men’s ATP Tour and Challenger Tour and publishes men’s tour rankings |
| ITF | Oversees the rules of tennis and competitions such as the Davis Cup |
| Grand Slam tournaments | Run four independent major events that award ATP ranking points |
| WTA | Organizes the main professional tour for women’s tennis |
There is also a useful bit of history behind the ATP’s influence. In 1973, many male players withdrew from Wimbledon after the suspension of Yugoslav player Nikola Pilić. The dispute showed how collective player action could affect a major tournament and helped establish the ATP as an important representative body.
Why the ATP matters to tennis fans
For fans, the ATP is a practical guide to the men’s season. Its calendar helps explain why players move from hard courts to clay and grass, while the rankings show what is at stake at each stop. A player defending points from a strong run the previous year may face more ranking pressure than someone with little to defend.
The tour structure also helps put a match in context. A young player making a run at a Challenger event may be building the ranking needed to enter ATP Tour draws. A top player at a Masters 1000 event, by contrast, may be chasing a high-value title or trying to qualify for the ATP Finals. Those different goals add meaning to results beyond the scoreline.

Final Thoughts
The Association of Tennis Professionals organizes the backbone of men’s professional tennis: its main tour, Challenger pathway and ranking systems. It shares the sport with other bodies rather than controlling every event. Once you understand that split, the rankings, tournament categories and weekly schedule become much easier to read—and the stakes behind each match become clearer.
